A golf club with a mass of .85 kg hits a golf ball with a mass of .075 kg. The golf ball was initially at rest. After being hit, it is moving at 35 m/s. The golf club and the golf ball were in contact for .015 s. Calculate the following: (4 points each part) a) The acceleration of the golf ball

b) The force exerted on the golf ball by the club

c) The force exerted on the golf club by the ball

d) The acceleration of the golf club

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
