A 10.0 kg ball rests suspended by the 5.0 m long weightless string. It experiences a central perfectly elastic collision with the 10 gram ball traveling at 800m/s.
Calculate:
The maximum change in height the big ball will gain after the collision
The maximum deflection angle for the large ball.
Calculate the torque required to accelerate the Earth in3days from rest to its present angular speed about its axis. Calculate the average power required
The rock strikes the ground a horizontal distance of 44 m from the base of the building. Assume that the ground is level and that the side of the building is vertical. How long did the rock take to hit the ground? Give your answer in seconds to two d..
The function y(x, t) = (25.0 cm) cos(?x - 20?t), with x in meters and t in seconds, describes a wave on a taut string. What is the transverse speed for a point on the string at an instant when that point has the displacement y = +22.0 cm?
A 12 volt battery powers a circuit that consists of a ten ohm resistor in series with a ten ohm and a 15 ohm that are in parallel. How much current flows through the 15 ohm resistor
Mercury flows through a horizontal pipe 1.40 cm in diameter and 0.6 m long. what is the rate of flow through the tube
You push on the chair with a force of = 37.0 directed at an angle of 43.0 below the horizontal and the chair slides along the floor. Using Newton's laws, compute the magnitude of the normal force that the floor exerts on the chair.
The velocity of the wave traveling on a string is higher if you increase the length of the string (keeping the kind of string, and the tension of the string, unchanged)
