What is its acceleration during the time it is stopping

Reference no: EM1362504

Q. 1. On a level road with its brakes on, a car traveling at 93 km/hr stops within 92 m when the brakes lock and the car slides.

a) What is the magnitude of the acceleration of the car?

b) What is the coefficient of kinetic friction between the tires and the pavement?

2. A car traveling at a speed of vo = 57 m/s stops smoothly (that is, its deceleration is constant) over a distance of d = 164 m

a) What is its acceleration during the time it is stopping? (Be careful about the sign!)

b) How long (what amount of time) does it take for the car to come to a stop?

c) After the car has gone 1/3 of the stopping distance, what is its speed?

d) If the car had been going 10 m/s but had stopped in the same d = 164 m distance, what would its acceleration have been?
