Equal forces are applied to a large truck and a motorcycle (both initially at rest) at the same time. After 5 seconds, the motorcycle is moving _(Faster, Slower, Same Speed)_than the truck.
What is the reasoning for the evidence for the motorcycle's motion in comparison with the truck?

If force is constant then a lower mass means lower acceleration.

If force is constant then a higher mass means greater acceleration.

If force is constant then a lower mass means greater acceleration.

If force is constant then a lower mass means equal acceleration.

An Ice Skater is coasting along the surface of a frozen pond with constant velocity. The force needed to maintain her motion is_(Greater than zero, less than zero, zero)_.
What is the reasoning for the evidence for the force needed to maintain her motion?

If velocity is changing then there is net acceleration, so net force needed.

If velocity is changing then there is net acceleration, so no net force needed.

If velocity is constant then there is no net acceleration, so no net force needed.
