General Physics 1 Exam 2 - Page 5 of 5 4/11/2022 4. (20 points) A 2.0kg box is forced up against a horizontal spring while resting on a flat table. The light spring has a force constant k = 75% and is compressed a distance of 0.35m. The box is released and moves across the table a distance of 60.0cm. Using the conservation of energy with a non-conservative force determine the coefficient of kinetic friction between the box and the tabletop 5. (20 points) A 100g ball strives a wall with a velocity of 5.00 and is found to rebound (bounce back) with a velocity of 4.75 (8) (10 points) Determine the impulse (6) (10 points) If the wall and ball interact for 250ms = 0.25s determine the average force exerted on the ball.
