is this right?if 5.0m/s^2=6.0m/s-0/1.2s
a=fn/m 5.0m/s=15.0N/3kg
show that the 5.0m/s^2 acceleration can result from a net force of 15N exerted on a 3.ok cart

1. I gather you went from 0 to 6 m/s in 1.2 seconds
that would be
a = change in V /change in time = 6/1.2
= 5 m/s^2 indeed
now
a = F/m = 15/3 = 5 m/s^2
