Three fire hoses are connected to a fire hydrant. Each hose has a radius of 0.013 m. Water enters the hydrant through an underground pipe of radius 0.094 m. In this pipe the water has a speed of 3.2 m/s.
The loop consists of a single turn of flexible conducting wire that is wrapped around a flexible mount such that the dimensions of the rectangle can be changed.
A white billiard ball with mass mw = 1.43 kg is moving directly to the right with a speed of v = 3.42 m/s and collides elastically with a black billiard ball with the same mass mb = 1.43 kg that is initially at rest.
A cube of mass m = 7.15 kg is placed on an inclined plane of mass M = 6.67 kg, which makes an angle ? = 48.30° with the horizontal. What is the normal force on the inclined plane from the table underneath it
