One object (m 1) has a mass of 2 kg and moves with a speed of 9 m/s to the right. another object (m 2) has a mass of 3 kg and moves to the left with a speed on 3 m/s. the two objects collide. after the collision, the first object (m 1) moves to the right with a speed of 1.5 m/s. the second object (m 2) moves to the right at 2 m/s. what is the change in the momentum of the first object (m 1) during the collision? (remember that "change" is always "final − initial".)

-15 Ns

Explanation:

= Mass of first object = 2 kg

= Mass of second object = 3 kg

= Initial Velocity of first object = 9 m/s

= Initial Velocity of second object = -3 m/s

= Final Velocity of first object = 1.5 m/s

= Final Velocity of second object = 2 m/s

Change in linear momentum is given by

Change in linear momentum of the first object is -15 Ns

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.
