a ball of mass 0.150 kg is dropped from rest from a height of1.25m. It rebounds from the floor to reach a height of 0.960m. What impulse was given to the ball by the floor?
What is the distance b between the beam formed by reflection off the top surface of the glass and the beam reflected off the bottom surface of the glass
Determine the capacitance of a Teflon-filled parallel-platecapacitor having a plate area of 1.90cm2 and insulation thickness of 0.0100 mm. What is the maximum voltage that can be applied to the capacitor?
A 4.20–kg block is set into motion up an inclined plane with an initial speed of vi = 7.40 m/s (see figure below). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of ? = 30.0° to the horizontal.
