The 70 kg crate shown in figure falls horizontally from a truck which is travelling at 70 km/h. If the crate slides 50 m on the ground without tumbling before coming to rest, determine the coefficient of friction between the crate and the road. Take initial speed of the crate as the speed of the truck.
Consider the horizontal
forces acting on the crate.
The initial velocity
of the crate can be written as
The coefficient of friction between the crate and the road is 0.385.
