solution:
here,
mass(m)=10 kg
acceleration due to gravity(g)=50
height(h)=10
we know,
potential energy(p.e)=m*g*h
=10*50*10
=5000
the potential energy is 5000.
Answer:
Here gravitational force is G or gravity constant.
Answer: 30 metres
Explanation:
Initial velocity of object = 120m/s
Time taken = 4.0s
Distance covered by object = ?
Recall that distance = (Change in velocity / Time taken)
Distance = (120m/s)/4.0s
= (120m/s) / 4.0s
= 30m
Thus, the object will be 30 metres high
It depends on the objects chemical composition.
