Suppose the wheel is rotated at a constant rate so that the mass has an upward speed of 4.37 m/s when it reaches a point p. at that moment, the wheel is released to rotate on its own. it starts slowing down and eventually reverses its direction due to the downward tension of the cord. what is the maximum height, h, the mass will rise above the point p?

A6,600 kg train car moving at +2.0 m/s bumps into and locks together with one of mass 5,400kg moving at -3.0m/s. what is their final velocity? +0.50 m/s -1.0 m/s +2.5 m/s -0.25 m/s

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
