Get started for freeA spring has an unstretched length of 10 cm. It exerts a restoring force F when stretched to a length of 11 cm.
a. For what length of the spring is its restoring force 3F?
b. At what compressed length is the restoring force 2F
A pile driver lifts a weight and then lets it fall onto the end of a steel pipe that needs to be driven into the ground. A fall of drives the pipe in . What is the average force exerted on the pipe?
At what speed does a 1000 kg compact car have the same kinetic energy as a 20,000 kg truck going 25 km/h?
Two identical horizontal springs are attached to opposite sides of a box that sits on a frictionless table. The outer ends of the springs are clamped while the springs are at their equilibrium lengths. Then a force applied to the box, parallel to the springs, compresses one spring by while stretching the other by the same amount. What is the spring constant of the springs?
Which has the larger kinetic energy, a 10 g bullet fired at
500 m/s or a 75 kg student running at 5.5 m/s?
