A 0.060 kilogram handball is thrown straight toward a wall with a speed of 10 m/s. It rebounds straight backward at a speed of 8.5 m/s.
(a) Determine what impulse is exerted on the wall?
(b) If the ball is in contact with the wall for 3.0 milliseconds, determine what average force is exerted on the wall by the ball?
(c) The rebounding ball is caught by a player who brings it to rest. During the process, her hand moves back 0.40 m. Determine the impulse received by the player?
(d) Find what average force was exerted on the player by the ball?
A 2.354 kg block is on a horizontal surface with ?k = 0.170, and is in contact with a lightweight spring with a spring constant of 526 N/m which is compressed. What is the velocity of the mass as it breaks contact with the spring
A light bulb has a resistance of 230 ?. It is connected to a standard wall socket (120 V rms, 60.0 Hz). Determine the current in the bulb
A 1.85 kg mass is attached to a light cordthat is wrapped around a pulley of radius 3.60 cm, which turns with negligible friction. Themass falls at a constant acceleration of 2.70 m/s2. Find the moment of inertia of the pulley.
