A ball weighing 1.78 N is shot through a launcher, achieving a speed ( from rest) of 41 m/s in 0.28 s.
A) What is the mass of the ball?
B) What is the acceleration of the ball as it moves through the launcher?
C) What average force acted on the ball to make it accelerate?

m=force/acceleration

acceleartion=finalspeed/time

Thanks you bob pursley. You got me in the right direction. I solved mass by w/g. I did not know force. I see now that the problems required an answer from the previous one to solve.
