The magnitude of the balls displacement is 9 meters.
Because if you push a car(toy car) and it starts to slow down then it is because of the friction from the wheels between the track. And if thee car does not slow down then it is because the slope is going diagnal and in the same nonstop speed. DOH

By removing the objects you choose to subtract from the group of objects.
Round objects don't have to roll down hill, they can slide if they have a heavier side, but are more likely to roll due to gravity.
gravity
If two round objects roll down a hill, the one with the greater mass will roll faster. If they are dropped they will fall at the same rate.
Gravity
A zorb is a large transparent ball in which someone may roll downhill.
If the cart is rolling downhill it will roll faster with mass, but on level ground or uphill it will roll faster without mass.
two round objects joined by a bar
The mass and the trajectory of the object affect the speed at which the object will roll.
The force that makes objects roll is gravity
They are already at the bottom of the hill. Can't roll down any further.
A pyramid will not roll and you cannot stack objects on top.
