Question

In an experiment, an object is released from rest from the top of a building. Its speed is measured as it reaches a point that is a distance d from the point of release. If this distance was doubled, what would the new speed be, assuming air resistance is negligible?

Answer:so the speed will increase by 1.44 times then the initial speed if the distance is increased to double

Explanation:As we know that the air friction or resistance due to air is neglected then we can use the equation of kinematics here

since we released it from rest so we have

so here we have

now if the distance is double then we have

now from above two equations we can say that

so the speed will increase by 1.44 times then the initial speed if the distance is increased to double
