Answer:
245 Newtons
Explanation:
The force needed is simply the same as that of gravity for an object with mass 25. That is: mass times g, which in this case gives 25 kg times 9,8 m/squared seconds. And that equals 245 Newtons.
Answer:
A student lifting a mass of 25Kg in vertical distance of 1.6 m in a time of 2.0 seconds requires a force of 245.25 N to lift the mass.
Explanation:
Given:
Mass m=25 kg
distance d =1.6 m
time= 2.0 seconds
To find :
Force required to lift the mass=?
We know
[tex]F = ma =mg[/tex]
where
g is a gravitational foce and is a constant [tex]g= 9.81ms^2[/tex]
[tex]F = ma[/tex]
Also [tex]F=mg[/tex]
substituting the given values,
[tex]F=(25kg)(9.81ms^2)[/tex]
[tex]F = 245.25N[/tex]
Result:
Thus ,a student lifting a mass of 25Kg in vertical distance of 1.6 m in a time of 2.0 seconds requires a force of 245.25 N to lift the mass.
