The correct answer to the question is : C)The problem is asking to solve for work; W = F × d
EXPLANATION:
As per the question, the distance covered by the object d = 29 m.
The force that acts on the object is F = 289 N.
We are asked to choose the correct equation for work done.
Work is said to be done on a body or by a body if the applied force has a component along the direction of displacement.
Mathematically work done W = force × displacement
= F × d
As per the question, we are given distance covered and applied force.
Hence, the correct equation for calculating work done by the object is equation C.
Answer:
2450 J
Explanation:
Given that,
A 50Kg girl jumps off a 5-meter-high diving board.
We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,
So, her kinetic energy right before she hits the water is equal to 2450 J.
