Answer: The time of contact will be 0.006 seconds.
Explanation:
An impulse of a force is the product of average force and the time interval when the force acts.
Mathematically,
[tex]J=F\Delta t[/tex]
Where,
J = impulse = 3.6 Ns
F = Force = 600N
[tex]\Delta t[/tex] = Time = ?s
Putting the values in above equation, we get:
[tex]3.6Ns=600N\times t[/tex]
t = 0.006 seconds
Hence, the time of contact will be 0.006 seconds.
