Help! I don't get this: ( very basic physics science)
It takes force of 300 N to accelerate an empty 100-kg car at 3m/s^2.
If a 160-kg wrestler is inside the car, how much force will be needed to produce the same acceleration?

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
