A pendulum of mass m= 0.8 kg and length l=1 m is hanging from the ceiling. The massless string of the pendulum is attached at point P. The bob of the pendulum is a uniform shell (very thin hollow sphere) of radius r=0.4 m, and the length l of the pendulum is measured from the ...

show that for a pendulum to oscillate at the same frequency as an object on a spring, the pendulum's length must be L=mg/k thank you

A bullet of mass 4.8 g strikes a ballistic pendulum of mass 3.3 kg. The center of mass of the pendulum rises a vertical distance of 9.7 cm. Assuming that the bullet remains embedded in the pendulum, calculate the bullet's initial speed. ....I'm getting an answer of 3002.05m/s ...

A pendulum and a mass spring system are both undergoing simple harmonic motion on Earth (use g = 10 N/kg). It is observed that every time the pendulum goes back and forth, the spring has gone up and down 14 times. If the pendulum has a length of 5 meters and the mass is 100 g...
