P/T=K, a masa y volumen constante

Abaseball has a mass of 0.145 kg and approaches a bat at 40.0 m/s. after it is hit, the ball leaves the bat at 50.0 m/s directly back. find the impulse of the bat on the ball. 7.25 kg*m/s 13.1 kg*m/s 5.80 kg*m/s 1.45 kg*m/s

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation
