A T shirt launcher launches shirts at 15 m/s. If it takes 0.30 s to accelerate a 250 g shirt to launch speed, determine the force exerted on the shirt. You can assume no friction.

I just need the final answer Please !

anonymous · Answer

a = f.v - i.v /t
a = 15 - 0 / 0.30

a 50ms^-2

F = ma...Let R represent frictional force

F - R = ma 
F - 0 = 0.250kg * 50ms^-2
Find the force :)
