The answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.

Why must you exert five times as much force to lift a mass of 5 kg as you must to lift a mass of 1 kg?
Because it's five times heavier of course !
How many pounds of force must a man exert on one end of a 10 ft lever to lift a 200 lb rock on the other end if the fulcrum is 2 ft from the rock?
to balance moment 10 feet x force = 2 feet x 200 force = 40 pounds
How to convert Normal Force lbf to Lift lbf?
Lift lbf = (Normal force lbf) x (cosine of angle of attack)
How does an inclined plane change how work is done?
vertical lift versus slope the work done is the same (force * distance), but with a say 30 degree slope you need only half the force but need to travel twice as far to raise the load the same height vertically
What is the force that enables planes to stay in the air?
Lift
How much is done if you exert a 25-N force to lift a ball 0.4 m in 2 s?
10 J (novanet)

Suppose you and your partner lift a bucket jointly the weight 50 Nthe angle between the your pulls in 90 degreeyour partner exert a force of 40 N .what is the force you exert?
You exert a force of 30 N.
How many newtons of force will you exert to lift 170gram weight?
A minimum of 1.667 newtons.
How many pounds of effort force would a user have to exert on the rope to lift the 60 lb load?
20lbs
How work done against gravitational force?
Lift any object. Grav. force is acting down, you must apply an upward force to lift the object. Work is force applied through a distance, so work is done if you lift it, but not if you hold it still.
When you use a ramp what happens to the distance over which you exert force?
The distance is longer than the lift or the drop, but the force you need is less than the weight of the load.
Why do you have to use force to lift objects?
Because there is a force of gravity constantly pulling it towards the center of earth. When you exert enough force to over come the gravity acting on an object it is lifted
If you exert a force of 10.0 n to lift a box a distance of 0.9 m how much work do you do?
Work done equals force times distance, so 10.0 times 0.9 is 9 joules.
Why must you exert five times as much force to lift a mass of 5 kg as you must to lift a mass of 1 kg?
Because it's five times heavier of course !
What minimum downward force needed to lift the 120 Newtons weight?
No matter how much force you exert downward, it shall avail you naught. No downward force acting directly on the object can ever succeed in lifting it.
Why do muscles burn when you exert yourself?
your muscles burn when you exert yourself because when you lift heavy or lift for an excess ammount of reps you get a build up of lactic acid in your muscles
