Resolved Question
Science question please help?
1.) A 15kg sled is moving at a speed of 4.0m/s. At what speedwillthe sled have twice as much kinetic energy?
2.) A 5kg cat is resting ontop ofa bookshelfthat is 3mhigh.What'sthe cats gravitational potential energy relative to the floorifthe accerelation dueto gravity 9.8m/s^2?
3.) What is the KE of a 98kg sky diver falling at a terminal velocity of 69m/s?
4.) A .62kg squirrel jumps from a tree branch that is 4.3m high to the top of a bird feeder that is 2.1m high. What is the change ingravitational potential energy?
5.) A small dog is trained to jump straight up at a distance of 3.2m. How much kinetic energy does the 8.2kg dog need to jump this high? (The acceleration due to gravity is 9.8m/s^2)
