Jack and Jill are maneuvering a 3400 kg boat near a dock. Initially the boat's position is < 2, 0, 3 > m and its speed is 1.1 m/s. As the boat moves to position < 4, 0, 2 > m, Jack exerts a force of < -420, 0, 210 > N, and Jill exerts a force of < 160, 0, 320 > N. How much work does Jack do?How much work does Jill do? How much work does Jill do?

Outside the space shuttle, you and a friend pull on two ropes to dock a satellite whose mass is 800 kg. The satellite is initially at position <3.7, -1.1, 2.7> m and has a speed of 6 m/s. You exert a force <-500, 400, 300> N. When the satellite reaches the position <2.6, 2.5, 16.5> m, its speed is 8.35 m/s. How much work did your friend do?

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, -1,2.0 > m and has a speed of 4 m/s. You exert a force < -400, 300, 250 > N. When the satellite reaches the position < 5.3, 2.6, -1.0 > m, its speed is 4.06 m/s. How much work did your friend do? Work done by friend = J

An 80 kg individual is in a seated position on a machine that tests knee extension strength. The calf length is 0.440 m, calf/foot mass is 5.8% of the body mass, calf/foot center of mass is 53% of the calf length from the knee joint, and calf/foot moment of inertia about the knee joint is 0.350 kgm2. The quadriceps moment arm is 0.040 m. The machine’s padding contacts the calf at a constant moment arm (does not change with knee...

A dart gun has a spring with a constant of 875 N/m. The spring is initially compressed 5.5 cm. You fire a 0.075-kg dart from a height of 0 m. The dart hits a wall at a height of 1.5 m. Ignore air resistance. What is the initial potential energy of the spring? What is the speed of the dart just before it hits the wall? The dart then penetrates 0.5 cm into the wall before coming to rest. How...

A 350 kg crate is being LOWERED by a person a distance 10 m with a force (FP) of 80 N(the person is pulling upward but the crate is moving downward). The rough ramp exerts a constant force of friction of 70 N. The angle that the ramp makes with the 0 floor is 30 . (a) Draw a free body diagram for the crate. (b) What is the work done by the person on the crate? (c) What is...
