​

Answer 1

Explanation:

a body of mass 10 kg is moving with a velocity of 5 m/s attainsvof 35m/s in 5 second find the force applied on body to change its velocity

20×10=200.

Hope it helpfull..

Answer 2

Given :

• Mass of body is 10 kg .
• Initial Velocity is 5 m/s .
• Final Velocity is 35 m/s .
• Time Taken is 5 sec.

To Find :

• Force Applied

Solution :

Firstly we will find Acceleration :

Using 1st Equation :

$\longmapsto\tt\boxed{v=u+at}$

Putting Values :

$\longmapsto\tt{35=5+a(5)}$

$\longmapsto\tt{35-5=5a}$

$\longmapsto\tt{30=5a}$

$\longmapsto\tt{a=\cancel\dfrac{30}{5}}$

$\longmapsto\tt\bf{a=6\:{m/s}^{2}}$

So , The Acceleration of the body is 6 m/s² ...

Now ,

For Force :

Using Formula :

$\longmapsto\tt\boxed{Force=Mass\times{Acceleration}}$

Putting Values :

$\longmapsto\tt{10\times{6}}$

$\longmapsto\tt\bf{60\:N}$

So , The Force is 60 N ...
