Answer:
6 km./hr.
Explanation:
Because 36 and 6 are rational numbers they can divided. So I divided 36 an 6 to come up with my answer

Answer:
The speed of stone traveling when it hits the ground = 49 m/s
Explanation:
Height of drop = 122.5 m
Given that distance the stone travels from its starting point
s(t) = 4.9t²
Substituting height
122.5 = 4.9t²
t² = 25
t = 5 seconds
So after 5 seconds stone hit the ground, we need to find velocity when t = 5 seconds.
Differentiating displacement with respect to time to get velocity,
s'(t) = 4.9 x 2 t = 9.8 t
Velocity when t = 5, s'(5) = 9.8 x 5 = 49 m/s
The speed of stone traveling when it hits the ground = 49 m/s

When you are holding the ball it has potential energy and when you through it it will then have kinetic energy as it go's up then it will pause for a brief sec. and then that 's when it has the greatest potential energy and then when it falls back down is when it has the greatest kinetic energy. The mechanical energy would be when you through the ball.

54-(15x2) divided by 2 = 12
54 - 15 = 39
39-15=24
24 divided by 2=12
