A baseball bat exerts an average force of 600. newtons east on a ball, imparting an impulse of
3.6 newton•seconds east to the ball. Calculate the amount of time the baseball bat is in contact with
the ball. [Show all work, including the equation and substitution with units.]



Answer :

Impulse= Average force * time
Time= Impulse/ Average force
= 3.6 newton *sec/ (600 N, east) 
time = 6.0*10^-3 seconds

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.
