A body builder exerts 15 N of force over 3 m. How much work did she do?
2 answers:
Work done = force x distance
work done = 15 x 3
work done = 45J
Answer:

Explanation:
Work is the force the causes the movement or displacement of an object. It is the product of force and displacement.

The force is 15 Newtons and the displacement is 3 meters.
Substitute the values into the formula.

Multiply.

1 Newton meter is equal to 1 Joule, so our answer of 45 Newton meters is equal to 45 Joules.

Do you have a question to ask ?
Calculate force of each car:
P1 = 900 kg x 12m/s = 10,800
P2= 600 x 24 = 14,400
Degree of travel = arctan(14,300/10800)
Degree of travel = 53.1 N of E
You're going to use the constant acceleration motion equation for velocity and displacement:
(V)final²=(V)initial²+2a(Δx)
Given:
a=0.500m/s²
Δx=4.75m
(V)intial=0m
(V)final= UNKNOWN
(V)final= 2.179m/s
