If the mass of the cart is 10, 000 g and it travels from point A to point C which has a height of 20 meters, what is the amount of mechanical energy at point A? Given Require: ME 10,000g = 10kg Solution ME=KE + PE V= D/T V=20/2.04 T-D/S v-9.8m/s PE = mgh KE 2 T-20/9.8 T=2.04s PE=10*9.8*20 PE 1960J
2. If the amount of kinetic energy at point B is 1000 J how much PE is there at point B if the cart travelled from point A? Given: Require Solution: 3. If the height of the cart at point D is 15.55 meters above the ground, what is the amount of kinetic energy at point D if the cart is now travelling from point C to point D? Given: 15.55 meters Require: KE Solution KE=my² 4. How fast is the cart while travelling from point A to point C? Given: Require Solution:
