-- If 2,000 newtons of force were applied through a distance of 1,000 meters,
then 2,000,000 newton-meters = 2,000,000 joules of work were done.
-- 45 minutes = (45 x 60) = 2,700 seconds
-- Power = (work) / (time) = (2,000,000 j) / (2,700 s) = <u>740.74 watts</u>
Interestingly, that's almost exactly 1 horsepower. (0.99295... of 746 watts)
Answer : The force will be 4501.9
We can see that, two forces acting on the dummy in two different direction.
We know that, here two forces are given in perpendicular direction with each other.
We know the force is the vector addition law so, we will use the Pythagoras theorem for the resultant of the vectors
Now, the net force is

Two forces is given,


Now, the net force is



Hence, the force will 4501.9 N
Answer:
A greater period.
Explanation:
The period of a simple pendulum is given by the following formula:

Where:
- Length of the pendulum
- Gravity constant
Since acceleration due to gravity is smaller in the Moon, period will be greater.
