Chapter 3, Problem 3.50P

A cannon, located 60.0 m from the base of a vertical 25.0-m-tall cliff, shoots a 15-kg shell at 43.0° above the horizontal toward the cliff. (a) What must the minimum muzzle velocity be for the shell to clear the top of the cliff? (b) The ground at the top of the cliff is level, with a constant elevation of 25.0 m above the cannon. Under the conditions of part (a), how tar does the shell land past the edge of the cliff?

A cannon, located 60.0 m from the base of a vertical 25.0-mtall cliff, shoots a 15 kg shell at 43.0 above the horizontal toward the cliff. (a) What must the minimum muzzle velocity be for the shell to clear the top of the cliff? (b) The ground at the top of the cliff is level, with a constant elevation of 25.0 m above the cannon. Under the conditions of part (a), how far does the shell land past the edge of the cliff?
A 17.0-kg cannonball is fired from a cannon with muzzle speed of 950 m/s at an angle of 40.0° with the horizontal. A second ball is fired with the same initial speed at an angle of 90.0°. Let y = 0 at the cannon. (a) Use the isolated system model to find the maximum height reached by each ball. hfirst ball 19,025 second ball = 46,046 m m (b) Use the isolated system model to find the total mechanical energy of the ball-Earth system at the maximum height for each ball. Efirst ball Esecond second ball x This is the gravitational potential energy of the cannonball at height 19025. What other form of mechanical energy is present as well? J =7,671,263.6
Radical Albertan separatists are driving a tank at a constant speed of 10 m/s up a 45 degree mountain slope, in a vain attempt to invade British Columbia. Pursued by the Mounties, the tank fires a 10 kg watermelon, with muzzle velocity 25 m/s, back along its path. Ignore the distance from the muzzle to the slope. If the gun barrel is pointed 20 degrees above the horizontal as shown, how far is the melon from the tank (which keeps moving) when it finally strikes the slope below? Answer in m.
