Aball is rolling across a frictionless surface when it suddenly stops.

according to newton's first law, why is the following statement incorrect?

"the ball stopped because it was not hit with a strong enough force."

a.
each object has a limited amount of inertia, no matter how much force initially causes it to move.

b.
an object stops when it has no more potential energy to convert into kinetic energy.

c.
uniform motion continues in a straight line until the object in motion is acted upon by an external unbalanced force.

d.
force is the result of mass times acceleration, so it was the acceleration that was not sufficient to keep the ball moving.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
