Question

A truck is traveling at a speed of 23.0 m/s along a level road. A crate is resting on the bed of the truck, and the coefficient of static friction between the crate and the truck bed is 0.610. Determine the shortest distance in which the truck can come to a halt without causing the crate to slip forward relative to the truck.

Answer 1

force friction=mu(mg)

that equals ma so a=mu*g

vf^2=Vi^2+2ad put in a, find d

Answer 2

6.37
