Answer:

Step-by-step explanation:
given,
bead is released from the height = 24.5 m from bottom
radius of the loop = 9 m
acceleration due to gravity = 9.8 m/s
A be the top most point of the loop
Difference of elevation from the top
H = 24.5 - 2 x r
H = 24.5 - 2 x 9
H = 24.5 - 18
H = 6.5 m
now using conservation of energy
KE = PE






speed at point A is equal to
