Question

Force of 1000 Newton is applied on a 25 kg mass for 5 seconds. What would be its velocity?

Answer 1

★ Acceleration = F/m

= 1000/25 = 40 m/s²

Equation of Motion :

v = u + at

= 0 + 40 × 5

= 200 m/s

Answer 2

Explanation:

Given,

Force (F) = 1000 N

Mass (m) = 25 kg

Velocity (v) = ??

Now,

As we know,

$\boxed{\pink{F = ma}}$

F = ma

$a = \dfrac{F}{m}$

$a = \dfrac{1000}{25}$

$a = 40$

Here,

accleration = 40m/s²

Now, From Motion formula

$\boxed{\red{ v = u + at}}$

u = 0

a = 40m

t = 5sec

By sub. the values

v = 0+40 × 5

v = 200

Hence,

Velocity = 200 m/s
