3. The impulse-momentum theorem states that the impulse acting on an object is equal to the change in its .
4. To increase the impact force for a given change in momentum, the time of impact should be .
5. A larger force applied for a shorter duration can produce the same impulse as a smaller force applied for a longer duration.
True
False
6. In an isolated system, the total momentum before a collision is always equal to the total momentum after the collision.
True
False
7. A 2.0 kg ball moving at 5.0 m/s strikes a wall and bounces back at 3.0 m/s. Calculate the impulse imparted to the ball.
