A 70g rubber ball is thrown with a speed of 10 m/s at a floating 8g balloon. If the balloon is knocked forwards at 40 m/s, how fast is the ball moving after the collision? (Round to the nearest tenths place)

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

this would be about 43%
