L A worker drags a crate across a factory floor by pulling on a rope tied to the crate. The worker exerts a force of 443 Non
the rope, which is inclined at 38.0° to the horizontal. The floor exerts a horizontal resistive force of 106 N. If the weight of
the crate is 92.0 N calculate the acceleration of the crate in the vertical direction. Use g = 9.81 m/s2.

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
