A 300-turn wire loop with a 5.0 cm radius is connected to a 0.20 kg pulley by a lightweight rod. The pulley, which has a radius of 3.1 cm, is attached to a 4.2 kg block by a massless rope. The loop is in a 0.75 T magnetic field. When no current flows through the wire loop, the plane of the loop is parallel to the magnetic field, and the block attached to the pulley just touches the ground. However, when a 0.76 A current flows through the loop, magnetic forces cause the loop to rotate, which lifts the block off the ground. Calculate the angle the plane of the loop rotates relative to the magnetic field. How high off the ground is the block lifted

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you donβt find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
