Question

PLEASE HELP!!

Calculate the transfer of energy by a force of 15N when it movies the object by a distance of 5 m
a. In the direction of the force
b. In the direction at 60 degrees to the direction of the force
c. At right angles to the force

Answer 1

a. 75 joules

b. 37.5 joules

c. 0 joules

Step-by-step explanation:

work is defined as the product of force times the distance moved in the direction of the force

Given data

force F= 15N

distance S= 5m

1. In the direction of the force

`force= 15*5\\force= 75 joules`

2. In the direction at 60 degrees to the direction of the force

`force= 15cos 60* 5\\force= 15*0.5*5\\force= 37.5 joules`

3. At right angles to the force

`force= 15cos 90* 5\\force= 15*0*5\\force= 0 joules`
