In the elastic collision, the velocity of approach and velocity of separation is the same. The velocity of the separation after the collision will be 45 m/s.
<h3>What is collision?</h3>
The abrupt, violent coming together in direct contact of two bodies is known as the collision. a falling object and a floor are examples of collisions.
When the distance between two ships decreases while the bearings remain constant, a collision occurs.
Objects have an elastic collision. Before the collision, they approach one another V1= V2=45 m/sec
The velocity of the approach is found as;
As we know,
The velocity of separation is found as;
and, e=1 for elastic collision.
In the elastic collision, the velocity of approach and velocity of separation is the same.
Hence the velocity of the separation after the collision will be 45 m/s.
