Work Done by Non-Conservative Forces 13. (Note: Here, the non-conservative force increases the kinetic energy of the object.) Fireworks are used to celebrate the New Year. One such firework is the baby rocket, which is attached to a stick, ignited, and allowed to fly off. One such baby rocket of mass 200 g was launched from rest and follows an erratic path towards an altitude of 29 m above the launch point. If the ignitable material in the rocket provides 425 J of work via a non-conservative force, what would be the velocity of the rocket at 29 m? Ignore the effects of air resistance and the decreasing mass of the rocket.

Frictionless In Figure, block 1 of mass m1=1.5kg slides from rest along a frictionless ramp from height h =2.50 m and then collides with stationary block 2, which has mass m2 =2.00m1. After the collision, block 1 and block 2 slides combine together a region where the coefficient of kinetic friction is 0.500 and comes to a stop in distance d within that region. (c) Calculate the distance d.
Mitch throws a 132—gram lump of clay at a 636 g target, which is at rest on a horizontal surface. After impact, the target slides 5.5 m before stopping. If the coefficient of friction is 0.68, find the speed of the clay before impact.
rough surfice Smooth Swace feed 2.50m he 3.00m E; Ei + WNc m A 34.2 kg block slides with a velocity of 10.22 m/s to the right on a frictionless surface (as shown in the figure above). The block slides up a slope to a height of 3.00 m and then slides across a 2.50 m long rough surface with a coefficient of kinetic friction equal to 0.325. The block continues to travel to the right and bumps into a massless spring with a spring constant (k) equal to 2320 N/m. a) How much does the spring get compressed by the block with respect to its equilibrium length? Please answer with a positive number in units of metres, with 3 sig figs. Start with conservation of energy: Er = Ei + WNC , and show all steps. b) What is the potential energy stored by the spring when the mass comes to a stop? Please show the symbolic equation and then “plug in the numbers" to give a numerical answer in units of joules with 3 sig figs. c) What happens to the potential energy stored in the spring after the block stops…
A 80. kg hockey goalie is standing with his skates straight ahead, so there is no friction between his skates and the ice. In Play A, he catches a 0.20 kg hockey puck moving at 40. m/sec. In Play B, he catches a 8.0 kg medicine ball moving in the same direction at 1.0 m/sec. In which case is the goalie pushed back faster? Explain your reasoning, or show supporting work.
A volleyball player starts a serve by throwing the ball vertically upward. The 240g volleyball comes to rest at its maximum height. The server then hits it and exerts an average horizontal force of magnitude 6.2 N on the ball. Determine the speed of the ball after the player hits it if the average force is exerted on the ball for 600 ms.
