There is a cube of mass m with a v_0 of 0 at the highest point of a plane is inclined. This inclined plane has an angle of θ = 24° with respect to the horizontal and a height of 4.7 m. Once it is released, it is moving with a v=0.55 m/s at a distance d after the end of the inclined plane. The kinetic friction coefficient between the block and plane is μp = 0.1. The coefficient of...

(4) A block is released from rest slides down to the bottom of a plane of incline q from a height h; the block attains a speed Vbottom. An identical block is dropped and undergoes free-fall from the same height h and hits the ground with speed Vfree. (a) what is Vfree? (b) Since Vfree must be greater than Vbottom, calculate the coefficient of friction u between the block and the plane. [20 pts]

* Problem 11 - Free fall motion (20 points) You throw a ball vertically upward from the flat roof of a tall building. The ball leaves your hand at a point even with the roof railing, with an upward velocity of 12 m/s. On its way back down, it just misses the railing. Find (a) the position and velocity of the ball 1.5 s and 5 s after it leaves your hand; (b) the velocity of the ball when it...
