Answer:
Height reached will be 28.35 m
Explanation:
Here we can use the work energy theorem to find the maximum height
As we know by work energy theorem
Work done by gravity + work done by friction = change in kinetic energy
now we will have
so here the height raised by the stone will be 28.35 m from the ground after projection in upward direction
