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
The answer is A. shorter wires
Answer:
0
Explanation:
m = Mass of person
g = Acceleration due to gravity = 9.81 m/s²
d = Vertical height from the ground
F = Force = Weight = mg
Net work done would be
Hence, the work done on the person by the gravitational force is 0
