A: Some physical properties change, but the substance keeps its identity.
energy. It will not disrupt the picture developing process by overexposing too much light on the film.
No friction present means: Ek = Ep
So Ek = mgh = 10 * 9.8 * 2 = 196 J
Answer:
75.645 J
Explanation:
The kinetic energy is related to the mass and velocity by the formula ...
KE = 1/2mv²
For the given mass of 0.045 kg, and velocity of 41 m/s, the kinetic energy is ...
KE = 1/2(0.045 kg)(41 m/s)² = 75.645 J
__
The unit of energy, joule, is a derived unit equal to 1 kg·m²/s².
