Cars A and B are traveling in a section of a highway. Car B with a velocity of 20 m/s, and an acceleration of 2.5 m/s2 is behind Car A. Car A is rounding a curved section of the highway with a radius of 100 m at a rate of 12 m/s. Determine the velocity and acceleration which Car A appears to have if Car A accelerates round the curve at a rate of 5.3 m/s2.

Cars A and B approached each other on a straight road from points 460 m apart. A has an initial speed of 70 kph and is decelerating at the rate of 0.40 m/s2. B has an initial speed of 20 kph and is accelerating at the rate of 0.30 m/s2. When will the cars meet and how far will each have traveled?
Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. A motorist is about to enter the exit ramp of a highway. When it is 50m before reaching A (along the straight path), the motorist travels at 80km/h, decreasing at the rate of 0.5m/s2until it reaches B. After it reaches B, it travels at a constant speed. Determine the magnitude of the acceleration: just after A just before B just after B
The car is traveling at a speed of 60 mi/hr as it approaches point A. Beginning at A, the car decelerates at a constant 8 ft/s? until it gets to point B, after which its constant rate of decrease of speed is 3 ft/s² as it rounds the interchange ramp. Determine the magnitude of the total car acceleration (a) just before it gets to B, (b) just after it passes B, and (c) at point C. Use 1 mile = 5280 ft. 200' A B 300
A driver travelling at 50mph sees a hazard at a certain distance ahead. The driver then applies the brakes immediately, time is 2sec and begins slowing the vehicle at 10m/s^2. If the distance from the stopping point to avoid hitting the boulder is 10.28m, how far the car from the hazard upon perception.
2. A Hyundai Santa Fe travels a 1.30km levelled road from Bonifacio roundabout to City Lights Hotel in a minimum time of 45.60seconds. Given that the car accelerates and decelerates at 2.53 m/s², which starts from rest at the roundabout and coming to a stop at the Hotel, determine the maximum speed (in kph) and the time (in seconds) it travel at this speed. Assume time for acceleration and deceleration are equal.
The car is traveling at a speed of 60 mi/hr as it approaches point A. Beginning at A, the car decelerates at a constant 6.3 ft/sec? until it gets to point B, after which its constant rate of decrease of speed is 2.7 ft/sec? as it rounds the interchange ramp. Determine the magnitude of the total car acceleration (a) just before it gets to B, (b) just after it passes B, and (c) at point C. 181 238' Answers: (a) Just before B, a = ft/sec?

Car A is traveling at a constant speed va = 123 km/h at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. At the moment when A passes P, the police car begins to accelerate at the constant rate of 5.6 m/s2 untila speed of 176 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Neglect any nonrectilinear motion of P. VA Answer: s = i m
Car A is traveling at a constant speed vA = 127 km/h at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. At the moment when A passes P, the police car begins to accelerate at the constant rate of 5.0 m/s2 until a speed of 171 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Neglect any nonrectilinear motion of P.
