It's really just a small formula that takes the wall's normal and the incidence vector, and returns the reflected vector for you. We could figure out how much energy is lost during the collision if we wanted to; because energy is a scalar rather than a vector, this is done the same way in 2-D (and 3-D) as it is in 1-D. . If the collision is perfectly inelastic, calculate the speed and the direction of the players just after the tackle. I want to calculate the angle of a collision between A) The player character and B) the floor, a wall, or another character. (Collision is inelastic) Answer: Known: m 1 (Mass)= 2 Kg, Conservation of momentum: p i = m 1 u 1 + m 2 u 2 = p f = m 1 v 1 + m 2 v 2 Note that if one object loses speed in a given direction, u 1 x < v 1 x, that speed is transfered to the other object, u 2 x > v 2 x .
