An 18.3 kg block is dragged over a rough, horizontal surface by a constant force of 190 n acting at an angle of angle 31 degrees above the horizontal. the block is displaced 76.5 m and the coefficient of kinetic friction is 0.125.
(a) find the work done by the 190 n force. the acceleration of gravity is
9.8m/s2.
(b) find the magnitude of the work done by the force of friction.

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
