Answer 1

Answer #1

Acceleration = change in velocity/ time = (15-9)/1.4 = 4.286 m/s2

Force F = 1140(15-9)/1.4= 4885.71 N

Force Direction is opposite to car velocity direction.

b) using v² - u² = 2as

2(-4.286) S = -144

S=16.8 m

I'm driving down the highway in my car, at a speed of 25 m/s. Some jerk cuts me off and rapidly slows down, so I have to slam on my brakes to avoid hitting him. (a) If I brake for 5.0 s down to a speed of 15 m/s, what was my acceleration during that period? You may assume that my acceleration was constant. (b) What distance did I travel during the period in which I was braking?
