The graph below indicates the force on a tennis ball as a function of time. For a non-constant force, we can calculate the impulse as the area between the force graph and the time (horizontal) axis. (a) Calculate the impulse imparted to the tennis ball during this time. Show your calculation. (b) Assuming the tennis ball was essentially at rest before it was hit, what is the speed of the tennis ball after the force is applied? The mass of the tennis ball is 0.057 kg.

Consider the before- and after-collision momentum vectors in the diagram below. Determine the magnitude and direction of the system momentum before and after the collision and identify whether or not momentum is conserved. Finally, determine the magnitude and direction of the net external impulse encountered by the system during the collision. (Hint: Velocity and masses are give) System Momentum Before Collision: _________________________ System Momentum After Collision: _________________________ Is momentum conserved? _________________________ Net External Impulse During Collision: _________________________
A uniform disk of radius R has a circular hole of radius R/2 removed as shown in the figure. Locate the center of mass with respect to the center of the original disk. (Hint: Treat the hole as an object of negative mass. This one picture hint negative mass show all work
If the cart starts from rest, what will be its velocity after the impulse? Ignore the friction.
During the labortory, your found that impulse could also be related to motion in a certain way. Restate that simple mathematical realationship here. You also found a simple mathematical realationship between pairs of forces in certain situations. Restate that realationship here. Put these results together to draw a conclusion comparing the motion of two objects before and after a collision. You should be able to find a quantity, which will remain unchanged in a collision. Be sure to justify your reasoning.
