Impulse from croquet mallete problem

[in10sivkid]

A croquet mallete delievers an impulse of 8.83 N*s to a .44 kg croquet ball initally at rest. what is the speed of the ball immediately after being struck?

ok so I = Ft = change in momentum

and they give us just a mass...

so that would help with p = mv to find velocity...

but this problem seems there are two unknowns i would either need to know the force or the time...but they don't give us either...

help?

all you need is the velocity, and you have I.

ok...how does having impulse help me with finding velocity

The impulse is the change in momentum, and the initial momentum is zero. Momentum is mass times velocity. You know the mass.

ok so essentially then then impulse = momentum since the initial momentum = 0

so 8.83 N*s = (.44 kg) * V

then solve for V...??
if so wow that was kinda easy

Looks good. Some of them are easy
