Answer:

I rather suspect it’s neither idle curiosity, nor the fact that you have a burning need to accellerate an actual 20 kg body to 100 m/s that has prompted you to post your anonymous question.

Would I be correct in thinking it’s a homework question? One that aims to get you to work it out rather than one that is seeking the actual answer?

If so then I’m not going to give you the answer, but I’ll tell you one way you could work it out. Maybe you will recall that;

F = ma

where F is the force, m is the mass and a is the accelleration. Now you know the force and the mass and you want to know the accelleration. So it shouldn’t be too difficult to work out a, should it? In case you need a clue;

a = F/m

Now you need to know how long it will to reach 100 m/s whilst accellerating at the value you have just calculated. Something else you may recall is that;

v = u + at

where v is the final velocity, u is the initial velocity, a is accelleration and t is time. Now assuming that your 20 kg body is starting from rest (you don’t actually say, so it will have to be an assumption) then u = 0 so in this instance;

v = at

or

t = v/a

Now all you need to do is plug-in the numbers and do the maths!
