Questions

The rear side of a truck is open and a box of 40 kg mass is placed 5 m away from the open end as shown in figure. The coefficient of friction between the box the surface below it is 0.15. On a straight road, the truck starts from rest and accelerates with 2 ms^-2 . At what distance from the starting point does the box fall from the truck? (Ignore the size of the box.)

A skier starts from rest at point A and slides down the hill without turning or breaking. The friction coefficient is $μ$ . When he stops at point B, his horizontal displacement is s. What is the height difference between points A and B?

(The velocity of the skier is small, so that the additional pressure on the snow due to the curvature
can be neglected. Neglect also the friction of air and the dependence of $μ$ on the velocity of the skier.)
