Topic 3 Lesson 1-2 Check Redo requirement

Directions: You must complete this assignment before you are eligible for a redo for Topic 3 Lesson 1-2 Check. Your score must be at least a 8 or higher on this assignment before a redo will be scheduled. Please ask for this to be unsubmitted if you would like another attempt. Final submission must be completed by Thursday 12 1) A 750N mountain climber scales a 150m cliff. How much work is done by the mountain climber? 0 J 0.2 J 5 J 112,500 J 2) A water balloon launcher launches a 49 N water balloon across an open field. The water balloon travels 80 meters in 4 seconds from it's initial position at rest. How much power was generated by the water balloon launcher? 3920 J 980 J 15680 W 980 W 3920 W 3) How much power is required to pull a sled 5 meters in 2 seconds if you use 60N of force? 9 W 24 W 150 W 600 W 4) A golf ball with a mass of 45 g and ping pong ball with a mass of 4.5 g are both sitting on a shelf 3m from the ground. Which object has the most gravitational potential energy? they have equal GPE the golf ball has more GPE the ping pong ball has more GPE 5) A 2 kg object is moving at a constant speed of 20 m What is the kinetic energy of the object? 10 J 40 J 400 J 800 J 6) What is the Gravitational Potential Energy of a 9 Kg turkey on a helicopter hovering at 210 m above Cincinnati? 1890 GPE 18522 GPE 1890 J 18522 J When the spring is pushed downwards, the elastic potential energy is increased. When the spring stretches back to full length, the energy becomes kinetic energy and the bear is pushed upwards. Since the bear is moving higher off the ground, the bear is also gaining gravitational potential energy as the bear rises. When will the ball be traveling at the highest speed? when it is at the highest point in the air when it hits the kid's head when it leaves the kid's hands when it bounces off the backboard
