6. A massive truck collides with a less massive car. The force experienced by the truck is (less than, equal to, greater than) the force experienced by the car. The resulting acceleration of the truck is (less than, equal to, greater than) the resulting acceleration of the car. Please answer ASAP

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
