An explosion breaks an object initially at rest into two pieces, one of which has 2.2 times the mass of the other. If 8000 Joule were released in the explosion, obtain how much kinetic energy did the heavier piece get?
Joules
The shock absorbers in the suspension system of a car are in such bad shape that they have no effect on the behavior of the springs attached to the axles. Each of the identical springs attached to the front axle supports 341 kg.
A swing is made from a rope that will tolerate a maximum tension of8.00*102 N without breaking. Initially, the swing hangsvertically. The swing is then pulled back at an angle of60.0o with respect to the vertical and released fromrest. What is the ..
