# Quick Answer: How Much Work Must Be Done To Lift A 110 Kg Motorbike?

## How much power is required to do 100 J of work on an object in a time of 0.5 s?

How much power is required to do 100 J of work on an object in a time of 0.5 s? P = W/t = 100 J / 0.5 s = 200 W.

## How much energy is needed to lift a weight?

Lifting Weights: On earth it takes about 10 Newton-meters (N-m) of energy to raise a 1 kilogram mass to a height of 1 meter. Since 1 N-m equals 1 Joule, that’s 10 Joules. If it takes 1 second to lift the weight 1 meter, than you have converted 10 Joules of energy to potential energy in one second.

## Which if either requires more work lifting a 10 kg load a vertical distance of 2 m or lifting a 5 kg load a vertical distance of 4 m?

Bigger load: Work = ( 10 kg ) x (9.8 m /s²) x ( 2 m ) = 196 joules. Smaller load: Work = ( 5 kg ) x (9.8 m /s²) x ( 4 m ) = 196 joules. The work required is equal in both cases.

## How much force is required to lift a rock a vertical distance of 8 m if 80 J of work is done?

The force (N) required to lift a rock having a vertical distance of 8m and 80 J of W is 10 N.

## Which requires more work lifting a 50 kg sack?

Which requires more work: lifting a 50kg sack a vertical distance of 2m or lifting a 25kg sack a vertical distance of 4m? Answer= It is the same, for the product of each is the same; ( 50 kg ) (2 m) = (25 kg ) (4 m).

## How do you calculate work?

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

## How much energy does it take to lift 1kg 1m?

On earth it takes about 10 Newton-meters (N-m) of energy to raise a 1 kilogram mass to a height of 1 meter. Since 1 N-m equals 1 Joule, that’s 10 Joules. If it takes 1 second to lift the weight 1 meter, than you have converted 10 Joules of energy to potential energy in one second. That’s 10 Watts of power.

## How many watts does it take to lift a kg?

In testing skilled, elite weightlifters Garhammer discovered that the power output in terms of the benchpress for a male during a one repetition, max load lift is four watts per kilogram of bodyweight. As it applies to the deadlift and squat, the number increases to 12 watts per kilogram of bodyweight.

## How much force is required to lift a mass of 1kg?

So to lift this 1kg mass will take more than 9.8 N. 10 newtons of life would create a net force of 0.2 N so 0.2/1 = 0.2 meters acceleration. Note that, gravitational force is one side of the same coin, with acceleration on the other.

## What are two main forms of mechanical energy?

There are two main types of mechanical energy. They are motion energy and stored mechanical energy. Motion energy: This is the energy something has because it is moving (eg a speeding cricket ball). You can feel the effect of this energy if the cricket ball hits you.

## Which requires more work increasing a cars speed?

The work done is equivalent to energy. Therefore, the work can be compared to the kinetic energy. Since 109.89m J > 89.91m J, more work is required to increase the car’s speed from 50 mph to 60 mph.

## How many joules of work are done when a force of 10 N pushes it a distance of 10 m?

How many joules of work are done on an object when a force of 10 N pushes it a dis- tance of 10 m? (8.1) 10 Nx 10 m – 100 J rk is done.

## How much energy does a 50 kg rock have if it is sitting on the edge of a 15 m cliff?

How much energy does a 50 kg rock have if it is sitting on the edge of a 15 m cliff? 7350 J.

## How much work is done by a constant horizontal 20 N force pushing a 50 kg block a distance of 10 m on a horizontal surface?

How much work is done by a constant horizontal 20 – N force pushing a 50 – kg block a distance of 10 m on a horizontal surface? Answer Key: C Work is the product of the force on an object and the distance the object moves in the direction of the applied force. In this case, work = 20 N x 10 m = 200 J.
