A boat travels across a wide river. If the boat can travel at a speed of 12 mph and it’s pilot heads in a direction of 110 degrees, while the currents velocity is 3.5 mph at a heading of 180 degrees, what will be the final velocity of the boat?

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
