A 1100 kg racing car accelerates from rest at a constant rate and covers a distance of 675 m in 15 s. What is the car's acceleration? (in m/s2)
Homework Answers
initial velocity = V0 = 0 m/sec ( rest)
distance = S = 675 m
time = t = 15 sec
S = V0 *t + 1/2 * a t^2
675 = 0 + 1/2 * a * 15^2
675 = 112.5 *a
acceleration = a = 675 / 112.5 = 6 m/sec^2

A car starts from rest, and begins accelerating at a constant rate a1. It accelerates at this rate from a distance of 56.9 m 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 79.4 m from where it began decelerating. the entire tripfrom start to finish(starting and ending at rest) lasts for a duration of 19.1 s. a)what is the magnitude of...
