Question 19 of 31
If a bat with a mass of 5 kg and acceleration of 2 m/s2 hits a ball whose massis 0.5 kg in the forward direction, what is
the reaction force of the ball on the bat?

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
