Given data
*The given mass of the pendulum is m = 3 kg
*The given height is h = 0.3 m
The formula for the maximum speed of the pendulum is given as
*Here g is the acceleration due to the gravity
Substitute the values in the above expression as
Hence, the maximum speed of the pendulum is 2.42 m/s
Explanation:
angular velocity is given by
w = 0.626
now tangential velocity is
V = rw
= 25 x 0.626
= 15.65 m/s
