Question

how much time an object having mass of 10 kg will speed up from at pet per second to 30 metre per second if I did Newton force will be applied over it​

Answer 1

Answer:

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

∴ Acceleration of the object a=

m

F

=

100

500

=5 m/s

2

Using v=u+at

∴ 25=5+5t ⟹t=4 s
