Consider an inclined plane at an angle of 40.0°, with a kinetic coefficient of friction of 0.350 and a static coefficient of friction of 0.450. A block with mass of 50.0 kg is on the incline and initially at rest. A force of 535 N, parallel to the incline, pushes the block a distance of 10.0 m up the incline. Do the following:

a) Determine the speed of the object at the end of this displacement using Newton's Laws of Motion (theoretical v.1).
b) Simulate on IP and determine the % error in the speed v at the end of the displacement (experimental),
c) Repeat the above calculation using the Work-Kinetic Energy Theorem: AKE (theoretical v, 2). Determine the % error in the speed of the object at the end of the displacement.
d) Repeat the calculation again but include gravity by calculating the change in potential energy instead of the work done by gravity. Use: Wnc= ΔKE+ ΔPE (theoretical v. 3). Determine the % error in the speed of the object at the end of the displacement.

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
