Question

a force of 50 N acts on a stationary body of mass 10 kg for 2s.The acceleration produced in the body and velocity attained by it is

Answer 1

Hey mate!!

❄Your answers❄

Step-by-Step Explanation =>

Force =>50N

Mass => 10kg

Time => 2seconds

Now,let's find out acceleration first...

With the help of formula----_---->

${ \bold{f = m \times a}}$

We can find out acceleration....Just put the values of (f) and (m)

$= > { \bold{50 = 10 \times a}}$

$= > { \bold{ \frac{50}{10} = a}}$

$= > { \bold{a = 5}}$

So,the acceleration comes out to be 5m/s2

Now,
Find out the final velocity.

Initial velocity =0 because the body initially was at rest.

Formula =>

${ \bold{a = \frac{v - u}{t} }}$
We have to find out (v)

PUT THE VALUES.

$= > { \bold{5 = \frac{v - 0}{2} }}$

$= > { \bold{5 = \frac{v}{2} }}$

$= > { \bold{5 \times 2 = v}}$

$= > { \bold{10 = v}}$

So,the velocity comes out to be 10m/s.
