Problem 9.34 8 of 11 An 8.2 kg crate is pulled 5.5 m up a 30 incline by a rope angled 16° above the incline. The tension in the rope is 140 N and the crate's coefficient of kinetic friction on the incline is 0.25 Part A How much work is done by tension, by gravity, and by the normal force? Express your answers using two significant figures. Enter your answers numerically separated by commas Wr, W, W,- 666.84,-220.99, 0...
You are using a rope to lift a 14.5 kg crate of fruit. Initially you are lifting the crate at 0.500 m/s. You then increase the tension in the rope to 190 N and lift the Grate an additional 1.15 m. During this d motion, how much work is done on the crate by the tension force? Express your answer with the appropriate units ! Å * OO? W Value Units Submit Request Answer Part D Find the work done...
1. A stunt performer (m=60 kg) is launched from a cannon (safely). Inside the cannon the performer is launched straight up in the air, from rest to a speed of 30 m/s through an 8 m long cannon. a) (2 pts) How much energy is required to launch the performer? b) (2 pts) How much force is required to launch the performer? c) (4 pts) What is the performer's speed when they are 10 m above the ground? 2.
