Mass of base ball = 0.25kg

Time = t = 0.0075/s

Force = F = 18,500N

Impulse = J = ?

Formula = Impulse = Force x time

= 18,500x0.0075

= 138.75 N-S

Rounded: 140 kg

Answer:

Impulse, J = 140 kg m/s

Explanation:

It is given that,

Mass of the baseball, m = 0.25 kg

Force exerted on the baseball, F = 18,500 N

Time of contact of baseball and bat is, t = 0.0075 s

We have to find the impulse delivered to the bat. Impulse is defined as the product of force and time. It is also equivalent to change in momentum.

So, J = F × t

J=18500\ N\times 0.0075\ s

J = 138.75 N-s

or

J = 140 kg m/s

Hence, this is the required solution.

An object is moving in a straight line along the y axis. As a function of time, its position is given by the equation y=3.0+4.8x
romanna [79]

Answer:

Explanation:

<u>Instant Velocity and Acceleration </u>

Give the position of an object as a function of time y(x), the instant velocity can be obtained by

v(x)=y'(x)

Where y'(x) is the first derivative of y respect to time x. The instant acceleration is given by

a(x)=v'(x)=y''(x)

We are given the function for y

y(x)=3.0+4.8x +6.4x^2

Note we have changed the last term to be quadratic, so the question has more sense.

The velocity is

v(x)=y'(x)=4.8+12.8x

And the acceleration is a(x)=v'(x)=12.8
