Question

0.1 kg ball start from rest after 2 sec; it's velocity becomes 100m/sec applied force on the body is​

Answer 1

5. v=u+at formula and multiply with mass

Answer 2

Answer:

Here's your answer

Explanation:

Given => u = 0m/s

               t = 2s

               v = 100m/s

               m = 0.1kg

               f =?

               a =?

By 1st equation of motion

v= u +at

100 = 0 + a*2

100 = 2a

a = 100/2

a = 50m/s^2

Now , Force is given by

f = ma

f = 0.1 * 50

f = 5N

Hope you understand.
