Question

Emilio tries to jump to a nearby dock from a canoe that is floating in the

water. Instead of landing on the dock, he falls into the water beside the
canoe. Use Newton’s third law to explain why this happened. Hint: First
identify the action-reaction pair in this example.

Answer 1

This is derived from Newton's first law of motion; every object in motion tends to stay in motion, unless acted upon by a different force. But this relates to the third law because inertia was counteracted by another force, gravity.

Answer 2

Resistive force from canoe in backward direction

Step-by-step explanation:

As per Newton's third law of motion for every action, there is an equal reaction and that too in the direction opposite the direction of main action.

Here, the action reaction pair is the contact point of Emilio or the Canoe.

When Emilio tried to jump on the dock, he exerted an action force i.e the KE+PE in the forward direction but while jumping he pushed behind the canoe which in turn exerted resistive frictional force in the backward direction on Emilio which restricted him from jumping exactly on the dock .
