Answer:
h = 24.11 m
Explanation:
Given that,
The potential energy of the snowball is 520 J
The mass of the snowball is 2.2 kg
We need to find the height of the hill. The potential energy of an object is given by the formula as follows :

g is acceleration due to gravity
h is height of the hill

So, the height of the hill is 24.11 m.
Yes, it's true.
But 2nd Newton Law always come to play when the horse is to move forward because obviously the forces interact antagonistically and mass has to be accounted for.
That's what I think. Hope it's right, all the best.

Explanation:
The centripetal acceleration is given by

where v is the tangential speed and r the radius of the circular orbit.
For the car in this problem,

and r=40 m, so we can re-arrange the previous equation to find the velocity of the car:
