Input interpretation:

elastic collision


Equation:

v_(1, f) = (m_1 v_(1, i) + m_2 v_(2, i) + m_2 (v_(2, i) - v_(1, i)))\/(m_1 + m_2) | v_(2, f) = (m_1 v_(1, i) + m_2 v_(2, i) + m_1 (v_(1, i) - v_(2, i)))\/(m_1 + m_2) |  \nv_(1, f) | final speed 1\nm_1 | mass 1\nv_(1, i) | initial speed 1\nm_2 | mass 2\nv_(2, i) | initial speed 2\nv_(2, f) | final speed 2


Input values:

mass 1 | 1 kg  (kilogram)\ninitial speed 1 | 1 m\/s  (meter per second)\nmass 2 | 1 kg  (kilogram)\ninitial speed 2 | -0.5 m\/s  (meters per second)


Result:

final speed 1 | -50 cm\/s  (centimeters per second)\n= -1.118 mph  (miles per hour)\n= -1.8 km\/h  (kilometers per hour)\nfinal speed 2 | 100 cm\/s  (centimeters per second)\n= 2.237 mph  (miles per hour)\n= 3.6 km\/h  (kilometers per hour)
