Question

If the fly experienced a force of 100 N when it hits a 20000 kg vehicle,how big was the force on the vehicle?

Answer 1

Answer:

It takes 4 s

Explanation:

Correct option is

C

4 s

Given :    m=500 kg              F=1000 N             u=2 m/s            v=10 m/s

Acceleration of the vehicle        a=  

m

F

​  

=  

500

1000

​  

=2  m/s  

2

 

Using     v=u+at

∴   10=2+2t                    ⟹t=4  s
