Q. A 2200kg pile driver is used to drive a steel I-beam into the ground. The pile driver falls 5.00 m before coming into contact with top of the beam, and it drives the beam 16-cm farther into the ground before coming to rest. Using energy considerations, compute the average force the beam exerts on the pile driver while the pile driver is brought to rest.
What is the Bens kinetic energy
A 1kg ball released from horizontal attatched to a 2.5 m string collides ellastically with a 2 kg block at rest. what is the speed of the block after the collision.
A thick-walled hollow cylinder (inner radius=47 cm, outer radius=66 cm) rolls down a 7° incline. If it starts with a speed of 1.9-m/s, what is its speed after it has travelled 16 m? (m/s).
The train comes to a stop 6.0 m from the point at which it was released. What is the magnitude of train's acceleration after its wheel begins to stick.
A proton is initially at rest at a point where the potential is 455V. Sometime later the proton is at a point where the potential is 191V. If no force but the electrostatic force acts on the proton, what is its final kinetic energy.
Yusef pushes a chair of mass = 51.0 across a carpeted floor with a force (the subscript 'p' here is lowercase and throughout the question) of magnitude = 170 directed at = 35.0 below the horizontal. The magnitude of the frictional force between the c..
A pair of speakers separated by 0.700m is driven by the same oscillator at a frequency of 662Hz. An observer, originally positioned at one of the speakers, begins to walk along a line perpendicular to line joining the speakers. (Assume the speed o..
A child in danger of drowning in a river is carried downstream by a current that flows uniformly with a velocity of 2.0 meters per second.
A 8.0 x15 swimming pool slopes linearly from a 1 depth at one end to a 3.70 depth at the other. What is the mass of water in the pool.
A 0.360 kg croquet ball makes an elastic head-on collision with a second ball initially at rest. The second ball moves off with half the original speed of the first ball.
Two identical carts travel at 1m/s in opposite directions on a common horizontal surface. They collide head-on and are reported to rebound, each with the speed of 2m/s.
A 1.5 kg copper block is given an initial speed of 3 m/s on a rough horizontal surface. Because of friction, the block finally comes to test. If the block absorbs 85% of its kinetic energy, calculate its increase in temperature.
