You park your buddy’s car on an incline that makes an angle of 17.0° below the horizontal, sloping toward a cliff of height 55.0 m, overlooking the ocean, but you forget to set the brake. while you are walking and enjoying the view, the car’s transmission slips out of park, and it begins rolling toward the cliff edge. assume zero rolling friction and zero air resistance. given that the car rolls 29.0 m before flying off the cliff, what is the car’s velocity just as it leaves solid ground?

12 drag each label to the correct category. decide whether each statement describes mass or weight. measured in newtons measured in kilograms does not change when gravity changes === a gravitational force changes when gravity changes the amount of matter in something mass weight

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)

Holes drilled several kilometers into earth’s crust provide direct evidence about earth’s interior in the form of
