Q. A test rocket is launched by accelerating it along a 200 incline at 1.52 starting from rest at point. The incline rises at 35 above the horizontal, and at the instant the rocket leaves it, its engines turn off and it is subject only to gravity (air resistance can be ignored). Find out the greatest horizontal range of the rocket beyond point A.
Q. A crate is sliding down a ramp that is inclined at the angle of 33° above the horizontal. The coefficient of kinetic friction between the crate and the ramp surface is 0.479. Find the acceleration of the moving crate.
