Question

A force of 50 Newton constant of mass 10 kg It takes 2 seconds on the body. In the body The value of velocity generated will be. ​

Answer 1

Answer:

hope it helps you

Explanation:

f = 50n

m = 10kg

t = 2sec

               as the body is in motion ,

the work done = kinetic energy .

but , u = o

s = ut + 1/2 gt^2

= 1/2 * 10 * 2 * 2

    therefore , s = 20 m

now , work done = mgh

there fore , work done is = 50n * 20 = 1000J

now the object is in motion so ,

         work done = kinetic energy

1000 = 1/2 * m * v^2

therefore , m = 10root2 = 10 * 1.414

so the velocity of the body is 14.14m/s
