A 6 kg cart starting from rest rolls down a hill and at the bottom has a speed of 10 m/s. What is the height of the hill?

h = 5.09 m

Explanation:

Applying the Law of conservation of energy to this situation, we can write:

where,

h = height of the hill = ?

v = speed of cart at the end = 10 m/s

g = acceleration due to gravity = 9.81 m/s²

Therefore,

h = 5.09 m

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
