A 4.67-kg ball of clay is thrown downward from a height of 2.77 m with a speed of 4.81 m/s onto a spring with k = 1450 N/m. The clay compresses the spring a certain maximum amount before momentarily stopping.
a) Find the maximum compression of the spring.
b) Find the total work done on the clay during the spring's compression.
A electron is accelerated from rest by the potential difference of 350 V. It then enters a uniform magnetic field of magnitude 200 mT with its velocity perpendicular to the field.
Oppositely charged parallel plates are separated by 5.78 mm. A potential difference of 600 V exists between the plates. find the magnitude of the electric field between the plates
A single-turn circular loop of radius 8.00 cm is to produce a field at its center that will just cancel the earth's field of magnitude 0.7G directed at 70 below the horizontal north direction. Find out the current in the loop.
A robot probe drops a camera off the rim of the 389 m high cliff on Mars, where the free fall acceleration is 3.7 m/s^2. Find out velocity with which it hits the ground and the time required for it to reach the ground.
Block B rests on a smooth inclined plane of 21 degrees and block A hangs vertically. Compute the acceleration of the system if the mass of block A is 1.08 kg and that of block B is 5.9 kg.
An ion source is producing 6Li ions, which have mass 9.99 x10-27 kg and charge +e. The ions are accelerated by a potential difference of 30 kV and pass horizontally into the region in which there is a uniform vertical magnetic field of magnitude B..
In a physics lab experiment, a student immersed 201 one cent coins (each having a mass of 3.00) in boiling water. After they reached thermal equilibrium, she quickly fished them out and dropped them into 0.240 of water at 20 in an insulated contai..

A vertical square plate (10' x 10') is used to dam a channel. determine the total resultant force on the plate and the location
a 10,000kg open rail car rolls under a hopper at 1m/s. the hopper dispenses grain into the moving rail car, how much grain was loaded into the car
A radio station broadcasts at a frequency of 600,000 Hz. Know that radio waves have a speed of 3.00 x 10^8m/s, what is wavelength of these waves.
A woman stands on a scale in a moving elevator. Her mass is 60.9 kg, and the combined mass of the elevator and scale is an additional 819 kg. Starting from rest, the elevator accelerates upward. Through the acceleration, the hoisting cable applies a ..
