Answer:
1.23 m/s
Explanation:
p=mv
57.2 = 46.5v
v= 57.2/46.5
v= 1.23
If you want to verify your answer, just insert the value of v in the equation.
Answer:
A change in size, shape, or matter.
Explanation:
A physical change does not produce new substances. A physical change may only change the physical properties of a substance. a change in size, shape, or phase of matter.
Are there any options or is it not multiple choice.
in situations involving equal masses, chemical reactions produce less energy than nuclear reactions.
the formula for velocity is:
v= distance/time
distance= 80m
time=2 seconds
v=80/2
v=40ms-1
