A box slides down the frictionless ramp shown inFIGURE CP10.72, then collides with a spring whose spring constant is .
a. What is the maximum compression of the spring?
b. At what compression of the spring does the box have its maximum speed?
You have a ball of unknown mass, a spring with spring constant , and a meter stick. You use various compressions of the spring to launch the ball vertically, then use the meter stick to measure the ball鈥檚 maximum height above the launch point. Your data are as follows:
Use an appropriate graph of the data to determine the ball鈥檚 mass.
