Answer:
option c
Explanation:
Work is said to be done when a force moves a body over a distance, in the direction of force applied.
Work done = force x distance (in the direction of the force)
Therefore work = force x displacement
As displacement is distance in a specific or specified direction.

(a) The y-component or vertical velocity is calculated using:
Vy = Vsin(∅)
(b) The x-component or horizontal velocity is calculated using:
Vx = Vcos(∅)
C. The person's feet push backward on the sidewalk; the sidewalk pushes forward on the person.
This is due to our kick back motion forced on the sidewalk when we walk, and the resistance of us walking on it createsa push forward.
Hope this helps!
As per Newton's II law we know that
here we know that
so here we will have
so here if we need to increase the acceleration we need to increase the applied force while on increasing the mass or on increasing the friction force the acceleration will decrease.
So here correct answer will be
<em>A) force on the object.</em>
