Question

Outside the space shuttle, you and a friend pull on two ropes to dock a satellite whose mass is 600 kg. The satellite is initially at position < 4.0, -1.6, 2.0 > m and has
a speed of 5 m/s. You exert a force < -600, 400, 250 > N. When the satellite reaches the position < 2.8, 2.6, 3.8 > m, its speed is 6.77 m/s. How much work did your
friend do?
Work done by friend =

Power 14. In three situations a single force acts on a moving particle. Here are the velocities and forces: (i) i = (-41) m/s and F = (6î – 203) N; (ii) i= (21 – 3) m/s and F = (-2) + 7R) N; (iii) i = (-3î + j) m/s and F = (2î + 6j) N; Rank the situations according to the rate at which energy is being transferred, highest to lowest.
Suppose a box of mass 5 kg is initially at rest on a frictionless horizontal surface. A constant force of 10 N is applied horizontally to the box for 4 seconds, and then a 7 N force of the same direction is applied for another 4 seconds. (a) Find the total distance that the box traveled. (b) Find the total work done on the box.

Use conservation of energy to solve both parts of the following problem (initial kinetic energy + initial gravitational potential energy = final kinetic energy + final gravitational potential energy): A skydiver with a mass of 80.0 kg steps out of a hot-air balloon holding at an altitude of 1.00 km and opens their parachute at an altitude of 200. m. While they’re in free-fall, there is a total drag force of 50.0 N on them. Once the parachute has opened, there is a total drag force of 3.60 kN on them. (y = 0 at 200. m) (a) How fast is the skydiver going when they open their parachute? (b) How fast will they be going once they touch down?
The speed of a crate traveling on a horizontal frictional surface changes from vi=13 m/s to vf=11.5 m/s in a distance of d=8.5 m. (A) how long in seconds did it take for the crate to slow by this amount, assuming the acceleration is constant? (B) if the crate has a mass of 1kg, what is the power supplied to the crate by friction? (C) what is the coefficient of kinetic friction between the crate and the surface uk?
A stuntman with a mass of 87.0 kg swings across a moat from a rope that is 11.5 m. At the bottom of the swing the stuntman's speed is 7.95 m/s. The rope's breaking strength is 1,000 N. Will the stuntman make it across the moat without falling in? Yes/No (b)What If? What is the maximum speed (in m/s) that the stuntman can have at the bottom of the swing on this vine to safely swing across the river? m/s
3) An object initially traveling at a speed of 78 cm/s experiences a force that increases its speed uniformly up to 92 cm/s. This process takes 5.0 seconds. How far will the object travel during these 5.0 seconds in meters? (Hint: There are two parts to this question)
