Question

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 1

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

Answer 2

Answer: The time of contact will be 0.006 seconds.

Step-by-step 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* t`

t = 0.006 seconds

Hence, the time of contact will be 0.006 seconds.
