Ballistic Pendulum Calculator

Find projectile speed v = (m+M)√(2gh)/m from pendulum rise.

Input Data

Input Projectile mass m.
kg
Input Pendulum mass M.
kg
Input Rise height h.

Formula

v = (m+M)√(2gh) / m

post-collision speed u = √(2gh); momentum m v = (m+M) u

How to Use

  1. Enter projectile mass m and pendulum mass M.
  2. Enter rise height h.
  3. Get projectile speed v.

Case Studies

10 g projectile lifts 1 kg pendulum by 5 cm

v ≈ 100 m/s.

FAQ

Assumptions?
