How much more gravitational potential energy does a 1.0-kg hammer have when it is on a shelf 1.2 m high than when it is on a shelf 0.90 m high?
Answer to relevant QuestionsYou are told that the gravitational potential energy of a 2.0-kg object has decreased by 10 J. (a) With this information, you can determine (1) the object’s initial height, (2) the object’s final height, (3) both the ...A horizontal spring, resting on a frictionless tabletop, is stretched 15 cm from its unstretched configuration and a 1.00-kg mass is attached to it. The system is released from rest. A fraction of a second later, the spring ...A 1.00-kg block (M) is on a flat frictionless surface (Fig. 5.32). This block is attached to a spring initially at its relaxed length (spring constant is 50.0 N/m). Alight string is attached to the block and runs over a ...A 1.5-kg box that is sliding on a frictionless surface with a speed of approaches a horizontal spring. (See Fig. 5.19.) The spring has a spring constant of 2000 N/m. If one end of the spring is fixed and the other end ...A 1500-kg race car can go from 0 to 90 km/h in 5.0 s. What average power is required to do this?
