Overview
I need help with a Physics question. All explanations and answers will be used to help me learn.
PROBLEM STATEMENT:
A truck carries a crate which can slide. Suppose the truck and crate are traveling to the right at an initial velocity of v0 and the distance between the front of the crate and the front of the trailer is d0. The brakes are applied and the truck decelerates with constantacceleration and stops in time ts.
a.) Express the truck's acceleration aT < 0 in terms of velocity and stopping time.
b.) Assume the truck brakes hard enough that the crate slides to the right relative to the truck. The coefficient of friction (static and dynamic) is mu. Write the equations of motion for the crate, then express the relative acceleration of the crate with respect to the truck, ac/t before and after the truck stops. Express it in terms of the given quantities v0, ts, mu, and g.
