Momentum and Impulse: Coefficient of Restitution

Medium

(Originais Teachy 2023) - Question Medium of Physics

Imagine two skaters practicing on a skate track. The first skater, with a mass of 60 kg, is moving at a speed of 5 m/s towards the second skater, who has a mass of 75 kg and is at rest. They collide and, after the collision, the first skater moves with a speed of 2 m/s. Assuming the coefficient of restitution for this collision is 0.6. From this information, answer: (a) Calculate the velocity of the second skater after the collision. (b) Determine the relative velocity between the two skaters before and after the collision. (c) Using the relative velocity and the coefficient of restitution, verify if the values are consistent with the proposed situation.
