Question

If velocity of objects change from 6m/s to 10m/s in 2 second,what is forced applied on object if its mass is 5 kg.

a.5N

b.10N

c.15N

d.None of these​

Answer 1

Answer:

Explanation: acceleration,10-6/2=2,

F=m a=5×2=10N

Answer 2

Answer:

10N

Explanation:

Force = Mass * Acceleration

Acceleration = Velocity time

                      =    10 m/s  - 6M/S /  2s

                       =    4 m/s / 2S

                        = 2 m/s^2

Force = 5kg * 2/m/s^2

            =  10 kg m/s^2

            =   10N
