1. An explosive charge imparts a velocity of 10,350 feet per second to a mortar shell as it exits the muzzle of the mortar. If the mortar is elevated at 80 degrees what are the horizontal and vertical velocities on the mortar shell?
2. Themortar shellwas long, so you reduce the explosive charge such that imparts a velocity of 6,150 feet per second. Now what is the horizontal velocity of the mortar shell?
3. Themortar shellwas short and you cannot change the explosive charge. You determine that a horizontal velocity of 1,592 feet per second will put the mortar shell. To what angle should the mortar be elevated?
4. Can you place a 150 poundcopper block on a 30o incline steel surface and not have it slide off?
5. A cart loaded with a weight of 2,500 pounds rests on a ramp with an incline of 21 degrees. Its center of gravity is 12 foot above grade. What is the potential energy of the cart?
