For the car on a level air track, a student has a video clip that shows the car at positions x₁ = 0.580 m and x2 = 0.692 m in adjacent frames. The video clip was recorded at a frame rate of 15 frames/second. Find the average speed of the car in m/s. Enter the number only, not the unit. QUESTION 2 Now the air track is tilted so that it makes a 10° angle with the horizontal. The car is let go from rest at t = 0. Assuming negligible friction, how fast (in m/s) is the car going after 1.58 seconds? Use g = 9.81 m/s² for the free-fall acceleration.

Romeo lives in a bachelor apartment. Juliet lives in her own bachelorette apartment a floor below. On St Patrick's Day Romeo drops small green ceramic roses from his balcony to attract Juliet's attention. Juliet is looking out her window when she sees the roses go by. Her security camera measures the time for the each rose to pass the full height of her 1.0 m tall window as 0.123 s. How high above the top of Juliet's window is Romeo's hand?

The Moon is about 3.8 x 10° m from Earth. Traveling at the speed of light, 3.0 x 10° m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)? The same physics was responsible for the noticeable delay in communications signals between lunar astronauts and controllers at the Houston Space Flight Center. S

A "moving sidewalk" in an airport terminal building moves at a speed of 1.3 m/s and is of length 37.0 m. A woman steps on at one end and walks at a speed of 1.8 m/s relative to the moving sidewalk. a) How much time does she require to walk from one end to the other if she walks in the same direction the sidewalk is moving? b) How much time does she require to walk from one end to the other if she walks opposite to the direction the sidewalk is moving? Not: Need drawing with solution
A passenger in a train moving at 30 m/s passes a personstanding on a station platform at t=t'=0. Twenty secondsafter the train passes, the person on the platform determines thata bird flying along the tracks in the same direction as the trainis 800m away. Five seconds later, the bird is 850maway. Assume a constant velocity for all involved. a) Draw a coordinate system indicating the motion of bird andtrain in the grame of the observer on the platform b) What are the coordinates of the bird as determined by thepassenger? c) Find the velocity of the bird as determined by the observeron the platform and the train passenger.

Two-dimensional motion: Object A has a position as a function of time given by rA(t) = (3.00 m/s)t i + (1.00 m/s2)t2j. Object B has a position as a function of time given by r p(t) = (4.00 m/s)ti + (-1.00 m/s2)t2i. All quantities are SI units. What is the distance between object A and object B at timet= 3.00 s?
Slowing Down: The speed of an object moving through a viscous fluid is given byU(1) = A. c-br(a) If the numerical value of A (in SI units) is 5.20 and the numerical value of b (in SIunits) is 1.19, then what is the initial acceleration of the particle, at time / = 0?(b) How far does the particle move in the first 3.00 s?You may ignore gravity. The particle has the same density as the fluid.
