A bungee jumper with mass 62.0 jumps from a high bridge. After reaching his lowest point, he oscillates up and down, hitting a low point eight more times in 44.0 . He finally comes to rest 22.0 below the level of the bridge. What is the spring stiffness constant?

Strategy 9.1 Rotational Energy. A frictionless pulley has the shape of a uniform solid disk of mass 4.00 kg and radius 28.0 cm. A 3.90 kg stone is attached to a very light wire that is wrapped around the rim of the pulley , and the stone is released from rest. As it falls down, the wire unwinds...

cart traveling at 0.3 m/s collides with stationary object. After the collision, the cart rebounds in the opposite direction. The same cart again traveling at 0.3 m/s collides with a different stationary object. This time the cart is at rest after the collision. In which collision is the impulse...

can you help me with problem 2.3.9?

In the Figure below, R S is to be adjusted in value by moving the sliding contact across it until points a and b are brought to the same potential. (One tests for this condition by momentarily connecting a sensitive ammeter between a and b, if these points are at the same potential, the...

Two identical batteries of emf = 12.0 V and internal resistance r = 0.200 are to be connected to an external resistance R, either in parallel (See Figure below) or in series (See other Figure below). If R = 2.00r, what is the current i in the external resistance in the (a) parallel and...

A controller on an electronic arcade game consists of a variable resistor connected across the plates of a 0.220 F capacitor. The capacitor is charged to 5.00 V, then discharged through the resistor. The time for the potential difference across the plates to decrease to 0.800 V is...

A sensitive gravimeter at a mountain observatory finds that the free-fall acceleration is 9.0 10 3 {\rm m/s^2} less than that at sea level. What is the observatory's altitude?
