When a object collide on the floor in elastic collsion condition, the average force applied by object to the floor can be calculated as follows. Refer to figure.

¡á Basic condition
- Mass of the object: m (kg)
- Speed of the object: V1 (m / s)
- Angle to the floor: ¥è (deg)
- Elapse time of collision: t (sec)

¢¹ Change of momentum: ¥ÄP = m * ¥ÄV
- Since only the velocity in the y direction has changed,
 ¥ÄV = |-V1y-V2y|
 V1y = V1*sin(¥è) = -V2y
 ¥ÄV = 2*V1*sin(¥è)
 ¡Å ¥ÄP = 2*m*V1*sin(¥è)

¢¹ The force applied by the object to the floor
  F = ¥ÄP / t = 2*m*V1*sin(¥è) / t

*** Âü°í¹®Çå[References] ***

F = 2*m*V1*sin(¥è) / t
