Instantaneous Power

Power is defined in physics as the amount of energy transmitted or transformed per unit time. The watt is the unit of electricity in the International System of Units, equivalent to one joule per second.

A block of mass m = 1.34 kg (Block 1) at rest at Point A on an arc of smooth circular surface of radius L = 30 m. Another block of mass M = 3.22 kg (Block 2) is at the bottom of the arc as shown in Fig.6. The line between the center of the arc and Point A and the line between the center of the arc and Point B make an angle 0 = 35 deg. If Block 1 is released and slides on the arc and hits Block 2, Block 1 stops at Point B and Block 2 starts to move along the arc. What is the velocity of Block B right after the collision in m/s. Keep three significant figures for the answer. g= 9.80 m/s. There is no friction.

The dog stole the baby's dirty diaper that Kristan had just changed and was getting ready to throw away. The dog weighs 15kg and the diaper weighs 2kg. The dog runs outside and climbs up the stairs to the playhouse where it accidentally steps a little too far in the slide causing the dog to slide down the slide with the diaper in his mouth. The height of the slide is 1.5m high off the ground. What is the change of potential energy of the dog assuming it started at rest and slid all the way to the ground?
