Answer:
0.572 Hz
Explanation:
given,
length of simple pendulum, l = 0.76 m
mass of the bob, m = 365 g = 0.365 Kg
angle made from the vertical, = 12°
frequency, f = ?



f = 0.572 Hz
The frequency at which pendulum vibrates is equal to 0.572 Hz
Answer:

Therefore, highest point that the cannon ball reaches is 168.7m
Explanation:
the cannon is fired at an angle 30 o to the horizonatal with a speed of 155 m/s
highest point that the cannon ball reaches?

g = 9.8m/s2

Therefore, highest point that the cannon ball reaches is 168.7m
