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.]

Verified 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,

\(J=F\Delta t\)

Where,

J = impulse = 3.6 Ns

F = Force = 600N

\(\Delta t\) = Time = ?s

Putting the values in above equation, we get:

\(3.6Ns=600N\times t\)

t = 0.006 seconds

Hence, the time of contact will be 0.006 seconds.
