Robert decides it would be fun to jump off of the back of his canoe while fishing in the lake one day. after he jumps out of the canoe, he notices that the canoe is no longer in the same place from where he jumped. which statement best explains why this occurred? a) an object at rest stays at rest. reactivate b) an object in motion stays in motion. c) for every action, there is an equal and opposite reaction. d) the acceleration of an object is determined by the weight of the object and the force applied to it.

C) For every action, there is an equal and opposite reaction.

The action of Robert pushing away from the canoe caused the equal opposite reaction of the canoe pushing away from Robert.

the bal will not change its velocity.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
