When a 20kg child steps off a 3.0kg stationary skateboard with an acceleration of 0.5m/s^2, with what acceleration will the skateboard travel in the opposite direction?
-
Use f=ma
The force the child puts stepping off is 20*.5 = 10
Then the force on the skateboard is equal
F = ma-> a=f/a
and opposite so the acceleration is
10/3 =.3
Since the force is opposing the child it would accelerate n the opposite direction
