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.

An electric vehicle starts from rest and accelerates at a rate of 2 m/s2 in a straight line until it reaches a speed of 20 m/s
An electric vehicle starts from rest and accelerates at a rate of 2 m/s2 in a straight line until it reaches a speed of 20 m/s. The vehicle then slows at a constant rate of 1 m/s2 until it stops. (a) How much time elapses from start to stop? (b) How far does the vehicle travel from start to stop?

A train which is traveling at 73 mi/hr applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 56 mi/hr as it passes a point 1/2 mi beyond A. A car moving at 36 mi/hr passes point B at the same instant that the train reaches point A. In an unwise effort to beat the train to the crossing, t the driver "steps on the gas." Calculate the...

Prob. 2 A car starts from rest, accelerates at 1.5 m/s, and reaches a maximum speed vi. After that it decelerates at 2 m/s until it stops. During the entire process the car has traveled a distance of I km. (a) Sketch the velocity diagram of the particle during the process. (Leave vI as an unknown on the diagram) (b) Determine the maximum speed vi. (e) Determine the total time required.

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...
