What is the gravitational potential energy of the 6 kg cart as it sits the top of the incline?
1 answer:
There are some missing details in the question. Found them on internet:
- the mass of the cart is m=40 kg
- The height of the incline is h=300 m (see attached figure)
Solution:
the gravitational potential energy of an object is given by
where
m is the mass of the object
g is the gravitational acceleration
h is the height of the object above the reference point (usually taken as the ground)
By applying this formula, we find the potential energy of the cart at the top of the incline:
- the mass of the cart is m=40 kg
- The height of the incline is h=300 m (see attached figure)
Solution:
the gravitational potential energy of an object is given by
where
m is the mass of the object
g is the gravitational acceleration
h is the height of the object above the reference point (usually taken as the ground)
By applying this formula, we find the potential energy of the cart at the top of the incline:

The cart travelled a distance of 14.4 m
Explanation:
The work done by a force when pushing an object is given by:
where:
F is the magnitude of the force
d is the displacement
is the angle between the direction of the force and the displacement
In this problem we have:
W = 157 J is the work done on the cart
F = 10.9 N is the magnitude of the force
, assuming the force is applied parallel to the motion of the cart
Therefore we can solve for d to find the distance travelled by the cart:
