a horse moves a sleigh 1.00 kilometers by applying a horizontal 2000 Newton force on its harness for 45 minutes. what is the pow
tatyana61 [14]
--  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)

The sensor in the torso of a crash test dummy records the magnitude znd direction of the net force acting on the dummy.If the du
patriot [66]

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

F_{net} = \sqrt{{F_{1}}^{2}+ {F_{2}}^{2}}

Two forces is given,

F_{1} = 130.0 N

F_{2} = 4500.0 N

Now, the net force is

F_{net} = \sqrt{(130)^{2}+ (4500)^{2}}N

F_{net} = \sqrt{20266900}N

F_{net} = 4501.9 N

Hence, the force will 4501.9 N

A pendulum is swinging back and forth with a period of 2.0 seconds here on Earth. This pendulum is then brought to the Moon, whe
Kryger [21]

Answer:

A greater period.

Explanation:

The period of a simple pendulum is given by the following formula:

T = 2\pi \cdot \sqrt{\frac{l}{g} }

Where:

l - Length of the pendulum

g - Gravity constant

Since acceleration due to gravity is smaller in the Moon, period will be greater.
