Speedy Sue, driving at +30.0 m/s, enters a one-lane tunnel. She then observes a slow- moving van 200 m ahead traveling at +2.00 m/s (because it has engine trouble). Sue applies the brakes immediately and accelerates at -3.00 m/s2 to come to a stop. a)Determine the separation distance “s” between Sue’s car and the van as a function of time t, with t = 0 when Sue enters the tunnel. b)Determine the closest separation distance that Sue’s car came to the van.

A "superman" is sitting on a tree 98 m high with a child he has rescued from the claws of a tiger. Unfortunately, the child slips and falls with an initial velocity of zero. The "superman" realized what was happening 2 seconds later and flew to catch the child at a constant speed of 39.2 m s-1. Calculate : a) the time the "super man" will fly before catching the child. b) the distance the "super man" will fly to catch the child. Assume that the acceleration due to gravity, g = 9.8 m s-2.
Problem 2: Kinematics and vectors. An object is moving on the xy plane with velocities given by: V₂ x = (10.0-0.500t)1 and v = (-5.00t+0.025²) j Determine the following quantities: a. The displacement of the object as a function of time. b. The average velocity of the object from for the time interval from 0 to 10 s.
You’re speeding at 85 km/h when you notice that you’re only 10 m behind the car in front of you, which is moving at the legal speed limit of 60 km/hr. You slam on your brakes, and your car negatively accelerates at 4.2 m/s2 . Assuming the other car continues at constant speed, will you collide? If so, at what relative speed? If not, what will be the distance between the cars at their closest approach?
An object's position in the as a function of time obeys the equation; x(t) = 14.2/t2.17 + 5.1t3 where all constants have proper SI Units. What is the speed of the object in the x direction at t = 1.93 seconds?
A Ford Territory and a Montero Sport are traveling in the same direction at 60.0 kph on a straight highway, parallel to each other, and the Territory is ahead of Montero by 248,90 kph. At a certain time, Territory decelerates uniformly at 2.50 m/s2, whereas the Montero accelerates uniformly at 2.0 m/s2. At what distance measured from the initial position of Montero will it overtake Ford Territory.
A driver, driving at a constant speed of 30m/s in a 50 mph zone, is unaware that he is being observed by an approaching police car (coming toward him from the front). At time t = 0, they are 800m apart and the police car has an approach speed of 40 m/s. When will the police officer catch up with the motorist? a) 80 s b) 68.6 s c) 11.4 s
Lisa in her Lamborghini accelerates at the rate of (2.20î - 2.20ĵ) m/s², while Jill in her Jaguar accelerates at (3.00 +2.00ĵ) m/s². They both start from rest at the origin of an xy coordinate system. After 5.00 s, find the following. (a) What is Lisa's speed with respect to Jill? m/s (b) How far apart are they? m (c) What is Lisa's acceleration relative to Jill? a = m/s²
Two green anacondas X and Y of length 10 m are moving in the same direction with a uniform speed of 20 kmph, with X ahead of Y. Upon detecting prey, Y decides to overtake X. Thus it accelerates by 1 m/s2, after 50 s the tail of Y slithers past X’s head. Calculate the original distance between the two?
A car travels on a road that is parallel to a train track. The car stops at a traffic light and at the same time a train passes with a constant speed of 12.0 m/s. The car remains stopped for 6.0 s and then leaves with a constant acceleration of 2.0 m/s*. Determine: A) The time it takes the car to reach the train, measured from the moment it stopped at the traffic light. B) The distance that the car traveled from the traffic light until it reached the train. C) The speed of the car at the moment it reaches the train. The solutions should be : A) 22.4 s B) 268.8m C) 32.8m/s
Problem 4: A police car traveling at 95 km/h is traveling west, chasing a motorist traveling at 80 km/h (both velocities are with respect to the ground and are constant). Find: 1. The velocity of the motorist with respect to the police car. 2. If they are originally 250 m apart, in what time interval (in seconds) will the police car overtake the motorist.
In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, with a maximum speed of 183.58 mi/h. The one‐way course was 5.00 mi long. Acceleration rates are often described by the time it takes to reach 60.0 mi/h from rest. If this time was 4.00 s, and Burt accelerated at this rate until he reached his maximum speed, a. how long did it take Burt to complete the course? b. Sketch position vs time, velocity vs. time, and acceleration vs. time graphs for the race.
Two cars are driving, car 1 has initial position -3500m, initial velocity -55m/s and acceleration +1.25m/s2, car 2 has initial position +4100m, initial velocity -35 m/s and acceleration +0.75m/s2; a) How much time until they collide? b) What is the x location where they collide, and the final velocity of each car?
