Question

A bin is given a push across a horizontal surface. The bin has a mass *m*, the push gives it an initial speed of 2.50 m/s, and the coefficient of kinetic friction between the bin and the surface is 0.150.

(a)Use energy considerations to find the distance (in m) the bin moves before it stops.

(b)**What If?** Determine the stopping distance (in m) for the bin if its initial speed is doubled to 5.00 m/s.

Step 1

Given; Initial speed, v = 2.50 m/s

Coefficient of kinetic friction = 0.150

Find: (a) Distance the bin moves before it stops

(b) The stopping distance for bin if its initial speed is doubled to 5 m/s

Step 2

From work-energy theorem, the kinetic energy of body is lost in work done against friction. That is:

Step 3

(b) If initial speee is doubled, v = 5 m/...
