a force used to lift a 12-kilogram mass to a height fo 8 meters in 2 seconds does 1040 joules of work. how much force is used.

130

Well, lifting a 12-kilogram mass to a height of 8 meters in 2 seconds sounds quite impressive! Let's calculate the force used, shall we?

First, we need to recall the formula for work: Work = Force × Distance. In this case, the work is given as 1040 joules and the distance is 8 meters.

So, we can rearrange the formula to find the force: Force = Work ÷ Distance.

Plugging in the given values, we have Force = 1040 J ÷ 8 m.

Now, let's grab a calculator and do the math... *cue the calculator sound effects*.

*Beep boop beep boop*

The force used is 130 Newtons! Ta-da! That's how much force you'll need to lift that 12-kilogram mass to a height of 8 meters in 2 seconds. Don't forget to stretch before attempting it though!

To calculate the force used to lift the 12-kilogram mass to a height of 8 meters in 2 seconds, we can use the work-energy principle.

According to the work-energy principle, the work done on an object is equal to the force applied multiplied by the distance over which the force is applied. In equation form:

Work = Force * Distance

In this case, the work done on the mass is 1040 joules and the distance is 8 meters. Let's plug in these values into the equation and solve for force:

1040 J = Force * 8 m

To solve for force, we need to rearrange the equation:

Force = Work / Distance

Force = 1040 J / 8 m

Calculating this:

Force = 130 N

The force used to lift the 12-kilogram mass to a height of 8 meters in 2 seconds is 130 Newtons.

To determine the force used to lift an object, we can use the equation for work:

Work = Force × Distance

Given that the work done is 1040 joules, the distance is 8 meters, and the time taken is 2 seconds, we can calculate the force.

First, let's rearrange the equation to solve for force:

Force = Work / Distance

Now, substitute the given values into the equation:

Force = 1040 joules / 8 meters

To find the force, divide the work done by the distance:

Force = 130 Newtons

Therefore, the force used to lift the 12-kilogram mass to a height of 8 meters in 2 seconds is 130 Newtons.

force * distance = work

F * 8 = 1040
F = 1040/8
