If Luke pushes his sister in a wagon down the driveway that is 14 meters long and it takes 22 Newton’s of force how much work di
1 answer:
Answer:
308 J
Explanation:
The work done by a force applied parallel to a displacement is given by:
where
F is the magnitude of the applied force
d is the displacement
In this problem, we have
F = 22 N is the force applied
d = 14 m is the displacement of the wagon
Therefore, assuming that the force is parallel to the displacement, the work done is

Answer:
man will move in opposite direction with speed
Explanation:
As we know that man is lying on the friction-less surface
so here net force along the surface is zero
so if we take man + stone as a system then net change in momentum of this system will become zero
so here we have
here we have
