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

`d=79.9m`

Step-by-step 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=(0.5*24.42^2)/(0.38*9.8)`

`d=79.9m`
