A ramp with a height of 10.0 m has an inclination angle of 30 degrees. A 12.0 kg block is sitting on top of the ramp initially at rest. Assuming the ramp's surface is frictionless, calculate the block's acceleration amd velocity when it reaches the base of the ramp. How much force did the block experience down the ramp and what must the coefficient of static friction be in order for the block to not move?

(b) Which of the following is the best explanation for your prediction?I. The elevator is moving upward. This will cause a person to press down harder on the floor, giving an apparent weightgreater than mg.II. The elevator moves with zero acceleration, and therefore the apparent weight is equal to mg.III. Because the elevator is moving upward it is partially lifting the person, resulting in an apparent weight less than mgarrow_forwardYou are a forensic scientists and have called to examine skid marks at a crime scene after a car locked its brakes during emergency breaking, and the car slid along the road.
