Answer:

initial magnitude will be 9 N and direction will be to the right

Explanation:

force= 9N

mass m= 330 grams

acceleartion = a

from newtons 2nd law of motion we write

$F= \frac{\mathrm{dP} }{\mathrm{d} t}$

dP is the chage in momentum dt is time taken and F is the Force applied

$9N= \frac{\mathrm{dP} }{\mathrm{d} t}$

this shows that the rate of change of momentum is 9 N

we also know that F= ma

putting values we get

$9= 0.330\times a$

a= 27.27 m/sec^2

The direction of acceleration will along the direction of force applied. So will be the direction of change momentum as in F=ma, mass is the scalar quantity and direction of force dictates the direction of motion. Hence, initial magnitude will be 9N and direction will be to the right

The formula for work is:

W = F * d Where W is work, F is Force, and d is distance.

Without doing any math, it can be seen from the equation that work is directly proportional to the force applied and the distance it travels. The homerun hit both traveled more distance and had a grater force applied to it in order to achieve this distance (assuming both baseballs weighed the same). Based on this reasoning, it is valid to conclude that the baseball which was a homerun was the hit that accomplished more work.
