Physics
A ballistic pendulum is used to measure the speed of high-speed projectiles. A bullet A weighing 22 g is fired into a 2.6-kg wood block B suspended by a cord of length l = 2.2 m. The block then swings through a maximum angle of θ = 60°.
a) The initial speed of the bullet is m/s?
b)The impulse imparted by the bullet on the block isJ?
c) The force on the cord immediately after the impact isN?
