The force applied to raise a table to a height of 8m when 120 Joules of work is done is 15 N. That is, Force F = 15N
<h3>
What is Work ?</h3>
Work is the product of force and distance in the direction of force. Work is done on an object when the displacement of the object is in the direction of the force applied. That is,
W = F x S
The S.I unit of work is Joule.
Given that a table to a height of 8m and 120J of work was done. To find the force applies, the parameters to consider are
Make force F the subject of formula from the formula written above. That is,
F = W/S
F = 120 / 8
F = 15 N
Therefore, if the 120 Joule of work is done, the force applied to raise a table to a height of 8m is 15 Newtons.

Incomplete question as the car's speed is missing.I have assumed car's speed as 6.0m/s.The complete question is here
An amusement park ride consists of a car moving in a vertical circle on the end of a rigid boom of negligible mass. The combined weight of the car and riders is 6.00 kN, and the radius of the circle is 15.0 m. At the top of the circle, (a) what is the force FB on the car from the boom (using the minus sign for downward direction) if the car's speed is v 6.0m/s
Answer:
Explanation:
Set up force equation
∑F=ma
∑F=W+FB
The minus sign for downward direction
