Question

a force of 10 N acts on a mass 2 kg .find out its velocity after 5 seconds .is the body were initialy at rest

Answer 1

given u=0

f=10N

m=2kg

time = 5 seconds.

-------------------------------------------------------------

to find - final velocity.

========================

calculation

F= Ma

10=2a

so, a=10/2=> 5m/s^2.

v=u+at

v= 0+ 5(5)

v=25m/s

Answer 2

here is your and dear
F=ma
so 10N= 2kg×a
a=10N/2kg
=5ms^-2
we know
a=change in velocity / time taken 5
initial velocity =0.
final velocity = 5
a=v-0/5
we know a=5ms^-2
so
5=v/5
v=5×5=25ms^-1
