Gravitational and Elastic Potential Energy _________-____ Hod: Date: Name: ___________________- Fe The highest-caliber cannon ever built [though never used} Is located in Moscow. Russia. The diameter at the cannon's barrel ls about 89 cm, and the cannon's mass is 3.6 x 10' kg. Suppose this cannon were lifted by airplane. If the potential energy associated with this cannon were 8.88 x 10' J. what would be its height above sea level? Assume that constant free-fall acceleration at this altitude is the same as at sea level. 1. 2. The force constant of the spring in a child's toy car is 550 lm. How much elastic potential energy is stored in the spring ifthe spring is compressed a distance of 1.2 cm? 3. With an elevation of 5334 In above sea level, the village of Aucanquiica. Chile, ls the highest inhabited town in the world. What would be the gravitational potential energy associated with a 64.0 lrg person in Aucanqullca? Assumethat the free-fall acceleration at Aucanqulica is equal to that at sea level. it 4. An arresting cable helps to slow jet planes as they land on an aircraft carrier. This is accomplished by two springs, each of which is attached to one end of the cable. Suppose the total elastic potential energy stored in the springs combined while a jet is landing is 5.78 x 10' i. if each spring is stretched 102m, what Is the force constant of the spring? 5 J! 10' Nlrn. Suppose the elastic potential energy 5. A pogo stick contains a spring with a force constant of 1. How far is the spring compressed? stored In the spring as the pogo stick ls pushed downward Is 120 i. E. An automobile to be transported by ship is raised 7.0 m above the dock. if its gravitational potential energy is 6.6 x 10'1, what Is the automobile's mass
