His major discovery was the theory of gravity and that mass has nothing to do with gravity
Answer:
10 m/s
Explanation:
Kinetic energy=
mv² where m is mass and v is velocity.
We have to make v the subject so we should rearrange the equation
K=
mv²
v²=
(use algebra)
v²= 7/0.5×0.140
v²=100
v=√100
v=10 m/s
We can confirm this by using the kinetic energy formula.
K=
×0.140×10²
K= 7 J
Hence it is proved that velocity is 10 m/s
