The Figure below shows a box with a mass of 20 kg sliding down an inclined plane which makes an angle of 55 with the horizontal. The coefficient of friction before the plane and box is 0.75. The air resistance along the plane is equal to 25v (in m/s). Assuming the box started at rest, determine the velocity and displacement at any time, t.

Mike Powell holds the record for the long jump of 8.95 m, established in 1991. If he left the ground at an angle of 15 . What was his initial speed?
According to the Guinness Book of World Records, the loingest home run ever measured was hit by Roy "Dizzy" Carlyle in a minor league game, with the ball traveling 188 m (i.e. 618ft) befor landing on the ground outside of the ballpark. Assuming the ball's initial velocity was 45.0 degress abbout the horizontal (ignoring air resistace), what did the initital speeed of the ball need to be to produce such a home run given that the ball was hit at a point 0.900 m (i.e. 3.00ft) about ground level. Assume the ground is flat and explain how the assuumption that the ground is flat is required to complete this calculation.

A block with a carpeted underside is pulled by a wheeled cart attached by a piece of cordage. If the two traveled at a constant acceleration down an inclined ramp (with a known angle), how would one go about finding mu s and mu k if values of position and time were recorded?
A block of mass m = 3 kg is sliding along a frictionless inclined surface that makes an angleof φφ = 300with respect to the horizontal surface.At the lowest points of the inclined surface, a projectile is fired at a speed of vv0 = 12 m/s thatmakes an angle θ0 = 450 with respect to the horizontal. Our aim of this problem is to find thetime when the projectile will hit the block. Find the time when the projectile hits the block. (Given, the initial distance between the blockand the projectile along the inclined surface at t = 0 is RR0 = 10 m as shown in the figure) Find the height h, where the projectile will hit the block.(c) Now assume that the projectile hits the block at its maximum range R along the inclinedsurface and the block is not sliding at all. Then find the maximum range along the inclinedsurface, RRmmmmmm = ?
