Question

Ball swinging on a rope. Mass of ball is 4kg. Assuming the mass of the rope and friction are both negligible, what is maximum speed of ball as it swings? (h=2.5m) Not sure but I think its 7m/s

Answer 1

P.E = K.E
Potential energy = kinetic energy

\[\sqrt{2*gravity*height}= Velocity\]

Height = 2.5
Gravity = 10m/s

Answer 2

Take g as 9.8.so you will get the answer as 7m/s
