1) A pitched baseball of mass .200kg, arives at home plate with a speed of 40m/s and is batted straight back to the picture (at the same height) with a return speed of 60m/s. neglect air resistance and determine the work done by the bat on the ball
2) a 140kg astonaut (including space suit) aquires a speed of 2.50m/s by pushing off with his legs from an 1800kg space capsule.
A) what is the change in speed of the space capsule?
B) if the push last .500s what is the ave force exherted by each other?

a 500 g ball swings in a vertical circle at the end of a 1.5-m-long string. When the ball is at the bottom of the circle the tension in the string is 15 N. What is the speed of the ball at that point?
A neutral (uncharged) capacitor has a charge of -3.00C moved from one of the plates to the other in a time of 5.00 sec, leaving +3.00C on the 1st plate. The +charges don't move, only the electrons. What was the average current?
