what is the vector change in velocity for a 0.140 kg baseball after 0.573s of acceleration by wind force 3.28N directly to East combined with 9.81 of acceleration due to gravity

for the answer, i got 14.551 m/s at 22.7 degree down of east.

all i need is for someone to confirm my answer or give me the correct answer.

thanks in advance :2thumb:

I think you need the initial velocity to find the change in velocity...

Assuming that initial velocity is 0

Your answer is correct.
