Answer:
No it will not make to the top of the hill
Explanation:
From the question we are told that
The velocity is
The height of the hill is
Generally from the law of energy conservation we have that
The kinetic energy of the pluck at the level position = The potential energy of the pluck at the maximum height the pluck can get to
So
=>
=>
=>
Given that the maximum height which the pluck can get to at this speed given in the question is less than the height of the hill then conclusion will be that the pluck will not make it to the top of the hill
