Question

in how much time an object having mass 110 kg will speed up from 5m/s to 25m/s if 500n force will be applied over it​

Answer 1

Answer:

Correct option is

B

4 s

Given :      m=100 kg               u=5 m/s              v=25 m/s         F=500 N

∴ Acceleration of the object          a=mF=100500=5 m/s2

Using      v=u+at

∴    25=5+5t                    ⟹t=4  s
