D. 1 BSEE, 1-A Module 5: IMPULSE AND LINEAR MOMENTUM Engaging Activity (25points) A. Solve the following. Illustrate and show the solution (5points each): 1. A particle of mass 2-Kg moves along X-axis with an initial velocity of 3 m/s. A force 6N (X-direction) is applied for period of three seconds. Find the final velocity. 2. A tennis racket strikes a tennis ball. The tennis racket and ball remain in the contact for 0.0005 seconds. The 50 gramball leaves the racket at speed of 80 m/s. Calculate the average force of the racket on the ball. 3. A marble of mass 0.04 Kg moving with a speed of 2.0 m/s strikes on a second marble, initially at rest with a mass of 0.04 Kg. As a result of the collision the first ball comes to rest and the second moves in the opposite direction. What is the velocity of the second marble? Ilagan, Angelica Marie C. BSEE, 1-A Date started: May 11, 2021 Date finished: May 28, 2021 Instructor: Perlas Janice C. Sandoval, Ed. D. 2 4. In a baseball game, a 2.0 Kg ball moving at 12 m/s is hit by a bat. After the impact, the ball moves in the opposite direction with a velocity of 18 m/s. if the force exerted on the ball by the batter is 670N, how long is the time of contact? 5. A 45 kg student is riding on a 7kg skateboard with a velocity of +4m/s. The student jumps of the cart with a velocity of -1m/s. Find the velocity o ...
