Question: The angular speed of the rotor in a centrifuge increases from 420 to 1420 rad/s in a time of 5.00s.[A] Find the magnitude of the angular acceleration.[B] Obtain the angle through which the rotor turns.
A car moves from a point located 26.0 m from the origin and at an angle of 35.0 from the x-axis to the point located 57.0 m from the origin and at an angle of 60.0 from the x-axis in 2.52 s.
Now the gymnast (not holding any additional mass) walks directly above right support. What is the force the left support exerts on beam.
A child slides down a slide with the 29 degree incline, and at the bottom her speed is precisely half of what it would have been if the slide had been frictionless. Compute the coefficient of sliding between the child and the slide.
The effectual coefficient of kinetic friction is 0.37. Compute the work done by the man on the piano.
A pump, submerged at the bottom of a well that is 34 m deep, is used to pump water uphill to the house that is 50 m above the top of the well, as shown above. All pressures are gauge pressures. Avoid the effects of friction, turbulence, and viscosity..

Because the mass would not make it around the loop if released from the height of the top of the loop (do you know why?) it should be released above the top of the loop-the-loop height.
What time would an observer on one of the two planets measure for the similar trip. Find out the coordinates of the center of gravity for this system.
A cart carrying a vertical missile launcher moves horizontally at the constant velocity of 30.1 to the right. It launches a rocket vertically upward. The missile has an initial vertical velocity of 40.33 relative to the cart.
