Question

The coefficent of static friction between the floor of a truck and a box resting on it is 0.38. The truck is traveling at 87.9 km/hr. What is the least distance in which the truck can stop and ensure that the box does not slide?

Answer 1

Answer:

$d=79.9m$

Explanation:

From the question we are told that:

coefficient of static friction $\mu=0.38$

Velocity $v=87.9=>24.41667m/s$

Generally the equation for Conservation of energy is mathematically given by

 $\mu*mgd = 0.5 m v^2$

 $d=\frac{0.5*24.42^2}{0.38*9.8}$

 $d=79.9m$
