Hello, New to physics. Trying to catch up since im an late enrolee.

Can you help me to solve these questions? Thank you!

Work, Power, Energy. 1. Two tugboats pull a disabled tanker with each tug exerting a force of 1.80 x 10 6 N, one with 14 west of north and the other 14' east of north. They were able to displace the tanker 0.75 km towards the north. What is the total work the tugboats do on the supertanker? 2. A 50.0kg marathon runner runs up the stairs to the top of a 443m tall tower. To lift herself to the top in 15.0 minutes, what must be her average power output? Express your answer in watts and in horsepower. (Hint: To get the work done as the runner climbs the tower, remember "Force x Distance") 3. If you drop a 13.0kg ball from a height of 30m (neglect friction).| a. How many Joules of Potential Energy does it have at the moment before dropping it? b. How many Joules of Kinetic Energy will it have when it is halfway through its fall
