Question1

A student decides to move a box of books into her dormitory room by pulling on a rope attached to a box. She pulls with a force of 160 N at an angle of 28.0° above the horizontal. The box has a mass of 22.0 kg, and coefficient of kinetic friction between box and floor is 0.300.

The student now starts moving box up a 10.0° incline, keeping her 160 N forces fixed at 28.0° above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of box?

Question2

Tarzan (m = 85 kg) tries to cross a river by swinging from a 10 m long vine. His speed at the bottom of swing (as he just clears the water) is 8.0 m/s. Tarzan doesn't know that the vine has a breaking strength of 1000 N. Does he make it safely across the river? Validate the answer.
