Unformatted text preview: TEST 1: A cube of height 1mm has a volume of? Which is a scalar quantity? A soldier at a defending enterance to a bay discovered a pirate ship 500 m away. He fired a canon with an initial velocity of 100 m/s with a 30 degree. He missed the first time. How long did it take the shell to hit the water? What was the range of the shell? What was the angle at which the shell was fired? 4 objects are held in position at the corners of a rectangle by a light rod. Find the moment of inertia of the system about the X-axis. A 20 Kg lamp is supported at the end of a horizontal beam. A cable at a 30 degree angle supports the lamp. What is the tension in the cable? Test 2:-Which is a vector? KE, momentum, spring potential constant, or gravitation potential-2 carts on a level one dimensional track. Cart A(1kg) is going right at 7 m/s, and cart B(3kg) is going left 3 m/s. Cart A rebounds (in opposite direction) with speed 3 m/s. What is velocity of cart B after collision?...
