The force is unbalanced. The canoe will accelerate to the left.

The runner accelerated then rested then accelerated faster than before and then turned around.
At 20 seconds the speed is half-ameter per second.
The graph overall shows an unbalanced parts but certain parts are balanced.

Object A is going at a constant speed while object B is accelerating.

People balanced. A car unbalanced. Walking at a constant speed in the same direction. The car that was at a constant speed suddenly stopped.

The average speed was 5 m/s. When a spaceship goes in space (theoretically) it should go on forever.

20 km/h. If an object has more force but the same acceleration it has a higher mass. So a car has a higher mass than a baseball if dropped of a cliff.
