A 500 gram block attached to an ideal spring (k = 80 N/m) oscillates on a horizontal frictionless surface. The total mechanical energy for the system is 0.075 Joule. When the spring is compressed by some distance x, the blocks speed is measured to be 24 cm/s. Find the compression distance (x) of the spring?
Raul pushes a stalled car with a force of 204 N. If the requiredforce decreases at a constant rate from 204 N to 44.0 N for adistance of 16.3 meters in 16.0 seconds, calculate the average power required to move the car.
