A 2 200-kg pile driver is used to drive a steel I-beam into the ground. The pile driver falls 4.20 m before coming into contact with the top of the beam, and it drives the beam 14.6 cm farther into the ground before coming to rest. Using energy considerations, calculate the average force the beam exerts on the pile driver while the pile driver is brought to rest.
Find the magnitude upwards?
Write down the equation for a transverse sinusoidal wave with an amplitude of 2.5 cm and an angular frequency of 2.90 rad/s that is moving along the positive x-direction with a wave speed that is 5 times as fast as the maximum speed of a point on ..
3 point charges are placed on the x-y plane: a +50.0 nC charge at the origin, a -50.0 nC charge on the x-axis at 10.0 cm, Find the total electric force on the +150 nC charge due to the other two
consider a direct vision prism. if a crown component n = 1.523 has an apex angle of 11. what is the apex angle of the flint component n = 1.72
A train at a constant 75 km/h moves east for 48 min, then in a direction 61.0° east of due north for 11min, and then west for 67 min.
display a pendulum bob is suspended from a pivot. show that if I draw the pendulum back by an angle θ, the center of the bob is elevated by the distance.
Find out the magnitude of angular acceleration of the wheel
A 12.00 kg block on a horizontal frictionless surface is attached to a light spring (force constant = 0.80 kN/m). The block is originally at rest at its equilibrium position when a force (magnitude P = 80 N) acting parallel to surface is applied t..
A factory worker pushes a 34.0 kg crate a distance of 3.7 m along a level floor at constant velocity by pushing horizontally on it, How much work is done on the crate by the normal force
What percentage of error in would be made if the moment of inertia of the pulley were avoid? Ignore friction in the pulley bearings.
Illustrate what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction.
What is the cross-sectional area of the wire. Nichrome wire of cross-sectional radius 0.786 mm is to be used in winding a heating coil. If the coil must carry a current of 8.00 A when a voltage of 3.00 x 10^2 V is applied across its ends.
Determine the value of the electric potential. calculate the acceleration of the ball when it is 3 cm from the surface and again at the position determined in part b.
