Asked by Eiban
A constant force of 100N , directed upward, is applied to a 5.0kg toy rocket by the rocket's engine.
What is the rocket's acceleration?
I used the equation a= F/m to get 20 m/s2 but it was wrong and I don't know where to go from here still?

You forgot the weight
weight = m g = 5(9.81) = 49 N
so 100 N up, 49 down
net force = 51 N up
a = F/m 51/5 = 10.2 m/s^2
weight = m g = 5(9.81) = 49 N
so 100 N up, 49 down
net force = 51 N up
a = F/m 51/5 = 10.2 m/s^2
