Two cars weigh 20000 Newton each. One car is parked. The other vehicle traveling with a speed of 55 miles per hour collides with the parked car in an inelastic collision. How much is the speed of the cars after the collision? ​

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
