A car with mass 1001 kg is traveling east through an intersection with a velocity of5.5 m/s when a truck of mass 1500 kg traveling north at 6.2 m/s collides with thecar. The vehicles ricochet; the car travels o with a speed of 3.5 m/s at an angle of30 and the truck travels o at a speed of vt m/s at an angle t. Find t in degrees.

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
