This lab activity is to use a ballistic pendulum.
- determine the speed of a projectile
- use conservation of energy and momentum
concepts and terms
- conservation of energy
- gravitational potential energy
- conservation of momentum
- inelastic collision
The velocity of a ball impacting a ballistic pendulum with an elastic collision is given by:
- obtain experimental data and analyse them
|v2 = 2 ||M2|| gR(1 − cos θ)
where M is the mass of the pendulum and ball combined, m is the mass of the ball, R is the distance from the pivot to the center of mass of the pendulum and ball, and θ is the angle from the vertical reached by the pendulum when the ball collides with it.
