The formula for kinetic energy is,
where m is mass and v is velocity.
Let's plug the given values in the formula.
It's kinetic energy is 64 Joules.
Answer:
Landed before it explodes
Explanation:
vf = vi + at,
0 = 145 - (9.8)t,
t = 14.79 s (Time to reach highest point)
14.79 x 2 = 29.59 s (Time to land on the ground)
It will have landed before it explodes because both the time to reach the highest point and the time to land on the ground are less than 32 seconds.
Due to friction from sliding against the ground, the player decelerates in 1 direction. Thus his momentum decreases.
Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is inversely proportional to its
I believe the answer to be no.
Because it is fully parallel with the law of Conversation of Energy.
But even so,according to the second law, some, or a even a small amount will be transformed(internal or thermal)
