A car starts from rest, and begins accelerating at a constant rate a1. It accelerates at this rate for a distance of 57.8m from its starting point, and then immediately begins to decelerate at a different constant rate a2, eventually coming to rest again after traveling an additional distance of 73.8m from where it began decelerating. The entire trip from start to finish( starting and ending at rest) lasts for a duration of 24.3s. a) what is the duration of the first part of the trip(acceleration phase)? b) What is the duration of the second part of the trip( deceleration phase)? c) What is the car's average speed over the course of the entire trip? d)what is the magnitude of the initial rate of acceleration, a1? e) What is the magnitude of the subsequent rate of deceleration, a2?

A car starts from rest and accelerates at a constant rate until it reaches 75 mi/hr in a distance of 220 ft, at which time the clutch is disengaged. The car then slows down to a velocity of 25 mi/hr in an additional distance of 570 ft with a deceleration which is proportional to its velocity. Find the time t for the car to travel the 790 ft.

2. A car moves along anx-axis through a distance of 900 m, starting from rest (at r-0 m) and stopping at x-900 m. It accelerates at +6 m/s through first 10 s of time. Then, through the remaining part of that distance, it slows down with constant acceleration until it stops. What are the: (a) car's maximum speed? (b) distance traveled during the first 10 s of time? (c) acceleration through the remaining part of the distance? (d) time elapsed...

1. A rocket accelerates upward from rest during the first stage with a constant acceleration of a1 = 95.0 m/s2 for t1 = 30.0 s. The first stage then detaches and the second stage fires, providing a constant acceleration of a2 = 50.0 m/s2 for t2 = 60.0 s. (a) What is the total distance traveled by the rocket during both stages? (b) What is the speed of the rocket after the second stage burn?
