The amount of force needed to keep a 0.3 kg box moving at a constant speed of r m/s of frictionless ice is?

A.) 0N
B.) 10N
C.) 1.2N
D.) 0.3N
E.) 2N

Answer 1

Answer:

0N

Explanation:

If an object is on one of these imaginary frictionless surfaces, the surface does not present any opposing force (frictional force) to slow an object sliding over it. Therefore no force is needed to keep the object moving.
