Question

A force of 1000 N is applied on a 25 kg mass for 5 seconds. What would be its velocity?

Answer 1

GIVEN:

force = f = 1000 N

mass = m =25 kg

time = t = 5 seconds

using the equation. f = ma

we get,a= f/m

=1000/25=40 m/s²

from first equation.

V = u + at

= 0+ 40 × 5

= 200 m/s.

∴ the velocity = V = 200 m/s

Answer 2

$\mathcal{\pink{\underbrace{\purple{Solution\::- }}}}$

Force applied = 1000N

Mass = 25kg

Time taken = 5 seconds

U = 0

V = ?

$\:\sf\underline{Acceleration\:=}\:$ $\boxed {A\:=\: \dfrac{force}{mass}}$

$\hookrightarrow\:\: \dfrac{1000}{25}$

$\hookrightarrow\:\:=\:\:40 \dfrac{m}{s}^{2}$

${\boxed{\large{\bold{V\:=u\:+at}}}}$

$\hookrightarrow\:0\:+40\:×\:5$

${\purple{\boxed{\large{\bold{=\:200 \dfrac{m}{s}}}}}}$
