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

Answer 1

Answer:

Under action of constant force

F=ma

V

2

−u

2

=20d

V=

2ad

=

m

2dF

V∝

m

1

1

Answer 2

From eqn of motion,

From eqn of motion,v2=2ad

From eqn of motion,v2=2ad-1 Now

From eqn of motion,v2=2ad-1 NowF=ma

From eqn of motion,v2=2ad-1 NowF=ma⇒a=(F/m) Putting ii in v2=2xm×α ⇒v=2Fd√m√ ∴αm√−−−√

hope its helpful.
