Question

A body of mass 5kg at rest .A force of 30N acts on the body find the acceleration produced in the body​

Answer 1

Answer:

please follow me....

Step-by-step explanation:

Given, mass of the body, m=5kg;

Initial velocity of the body, u=0;

Force acting on the body, F=20N;

Time for which the force acts, t=10s

If a is the acceleration produced in the body,

a=

m

F

=

5

=4m/s

Let v be the velocity of the body after 10 s.

Clearly, v=u+at=0+(4)×(10)=40m/s

Kinetic energy acquired by the body,

E

$\footnotesize\bold{\underline{\underline{\sf{\red{Formula\: Used:-}}}}}$

${\underline{\boxed{\sf{Force = Mass \times Acceleration }}}}$

$\footnotesize\bold{\underline{\underline{\sf{\red{Putting\: the\: values:-}}}}}$

$\leadsto \sf \: 30 = 5 \times Acceleration \\ \\ \leadsto \sf \: 30 = 5 \:Acceleration \\ \\ \leadsto \sf \: Acceleration = \cancel\dfrac{30}{5} \\ \\ \leadsto \sf \: Acceleration = 6 \: m/s {}^{2}$

$\star\small\sf\underline\blue{AnswEr:-}$

• The required acceleration produced in the body is 6 m/s².
