- 8. A friend throws a basketball to you as you are standing on a frictionless patch of ice. To make sure you gain as much speed as possible you decide to: * Catch the basketball and drop it Catch the basketball and hold onto it. Catch the basketball and throw it back towards your friend. Catch the basketball and throw it the same direction it was moving before you caught it. O Duck and don't allow the basketball to contact you at all.The upper mass is moving to the right with an initial velocity of 3 m/s.

- A cannon is fired horizontally from a platform (see figure). The platform rests on a flat, icy, frictionless surface. Just after the shell is fired and while it is moving through the barrel of the gun, the shell (mass 2.9 kg) has an acceleration of +2600 m/s². At the same time, the cannon has an acceleration of -0.72 m/s². What is the mass of the cannon? kg Cannon shell IceIn an experiment conducted at Carleton university, following experimental setup has been prepared.
