Fooly Cooly (soundtrack) Vol. 2: King of Pirates Title Page SRT Momentum PreTest.notebook November 25, 2012 A loaded cannon rolls to the right at 2 m/s when it fires a 10 kg cannonball. The cannon recoils to the left with a speed of 1.5 m/s. If the cannon alone has a mass of 600 kg, with what velocity does the cannonball leave the cannon? (1) 1 SRT Momentum PreTest.notebook November 25, 2012 Mr. Szarzak is driving down crescent in his 1,500 kg PT Cruiser at 12 m/s when he is struck from behind by Mr. Scott’s 1,000 kg Corolla. The bumpers tangle and the two cars roll down Crescent together at 15 m/s. How fast was the Corolla moving before the collision? (2) 2 SRT Momentum PreTest.notebook November 25, 2012 Mr. Szarzak and Mr. Scott are driving bumper cars during the Great America field trip. (Mr. Szarzak wants payback!) His car has a mass of 225 kg and is moving to the right at 2.5 m/s when he bumps Mr. Scott’s 200 kg bumper car which was initially at rest. If Mr. Szarzak’s car is slowed to 0.5 m/s, how fast does Mr. Scott’s car move after the collision? (3) 3 SRT Momentum PreTest.notebook November 25, 2012 A 70 kg girl jumps onto a force plate. Right before impact she is moving down at 2.4 m/s. The force stops her in 0.08s. How hard does the force plate have to push up on the girl to do this?
