The statement that best describes a perfectly inelastic collision is
C. A surfer falls off of his surfboard when a wave hits him.
What is collision?
A collision is the interaction between two bodies in such a way that the momentum and velocity of one body gets changed due to the presence of other body. There are three types of collision-
1. Elastic collision
2. Inelastic collision
3. Perfectly inelastic collision.
In all types of collision , the momentum of the system before collision and after collision always remains same or we can say that momentum is conserved in collisions
What is elastic collision
An elastic collision is the one in which kinetic energy is also conserved and coefficient of restitution is one. Both the bodies move separately with different velocities after elastic collision.
What is inelastic collision ?
In inelastic collision there is a loss of kinetic energy and coefficient of restitution is less than one.
What is perfectly inelastic collision?
In perfectly inelastic collision there is maximum loss of kinetic energy and coefficient of restitution is zero. Both the bodies stick together after collision and move with same velocity
What is coefficient of restitution ?
Coefficient of restitution is the ratio of relative velocity of separation after collision to relative velocity of approach before collision.
A surfer falls of his surfboard when a wave hits him is an example of perfectly inelastic collision because in this when water hits the surfers he falls of and sticks to the water , and will also now move with the velocity of water .
So when the surfer falls off his surfboard when a wave hits him is perfectly inelastic collision.
