Work and Energy Worksheet Section 1 Work: 1. A person pulls a toboggan for a distance of 35.0m along the snow. The force in the rope (tension) is 94.0N. How much work is done on the sled? Solution: W= Fd W= 94.0N x 35.0m W= 3290 Nm or J 2. The cable of a large crane applies a force of 2.2x10^4N to a demolition ball as it lifts it vertically a distance of 7.6m. a) How much work is done on the ball? b) Is the work positive or negative? Why? Solution:

QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)
