Question

The velocity acquired by a mass m in travelling a certain distance d starting from rest under the action of a constant force is directly proportional to:-
1) √m
2) m°
3) 1/√m
4) m

Answer 1

From eqn. of motion we get

$v { }^{2} = 2ad$
Now F=ma
So a=F/m

put this a=F/m in the 1st equation to get

$v = \sqrt{2df \div m}$
Thus answer is option 3
