A19 g bullet is fired into the bob of a ballistic pendulum of mass 1.3 kg. when the bob is at its maximum height, the strings make an angle of 60° with the vertical. the length of the pendulum is 2.3 m. find the speed of the bullet.

217.43298 m/s

Explanation:

= Mass of bullet = 19 g

= Mass of bob = 1.3 kg

L = Length of pendulum = 2.3 m

= Angle of deflection = 60°

u = Velocity of bullet

Combined velocity of bullet and bob is given by

As the momentum is conserved

The speed of the bullet is 217.43298 m/s

the amount of current in the coil
