The amount of force needed to keep a 0.1kg basketball moving at a constant speed of 6 m/s on frictionless ice is ___ N

Given that,

Basketball has a mass of 0.1kg

m = 0.1 kg

The basket ball is moving at constant speed, this shows that it is not accelerating. So, acceleration is zero

a = 0m/s²

The constant speed is 6m/s

v = 6m/s

So, force to keep it moving with this constant speed can be calculated using Newton second law of motion

F = ma

F = m * 0

F = 0N

So, since the basket ball is moving at constant speed, then, the force need to keep the ball moving is 0N.
