An NFL place kicker is practicing his extra-point kicks. He kicks the football into the wall of his living room and it hits at a speed
of 83 mph (or 37.1 m/s). If the wall did not move at all, how fast
would the ball bounce back? (Assume a perfectly elastic
collision and ignore friction.)
Note: Type your answer as m/s

scientific laws are the result of testing theories and proving them to be facts.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
