Astone thrown from a height of 5.72 meters hits the ground at 13.3, calculate the initial speed. neglect air resistance

12.31618 m/s

Explanation:

s = Displacement

t = Time taken

g = Acceleration due to gravity = 9.81 m/s² = a

Velocity is given by

The initial velocity is 12.31618 m/s

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

a=d/t

a="triangle"v/t

explanation:

a = acceleration
