Hi please help with the following: After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, the batter decides to keep going past second base and try for third base. The 59 kg player begins sliding 3.40 m from the base with a speed of 4.35 m/s. If the player comes to rest at third base, how much work was done on the player by friction?
1. After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, the battler decides to keep going past second base and try for third base. The 62.0-kg player begins sliding 3.4om from the base with a of 4.35m/s.If the player comes to rest at third base, (a) How much work was done on the player by friction?(b) What as the coefficient of kinetic friction between the player and the ground? Draw and explain.

A can of beans that has mass M is launched by a springpowered device from level ground. The can is launched at an angle of a0 above the horizontal and is in the air for time T before it returns to the ground. Air resistance can be neglected. (a) How much work was done on the can by the launching device? (b) How much work is done on the can if it is launched at the same angle a0 but stays in the air twice as long? How does your result compare to the answer to part (a)?
