Answer
rate of current = (1/x) mph
Explanation
let the distance from <span>Greentown to Glenavon be y miles and the rate of current be x mph.
y = (15+x)g
y = 15g+gx .........................................(1)
The distance from </span><span>Glenavon to Cambria = (y-2)
y-2 =(15-x)g
y-2 = 15g-gx
y = 15g - gx + 2 ....................... (2)
equation equation (1) and (2)
15g + gx = 15g - gx + 2
2gx = 2
dividing by 2g both sides we get,
x = 1/2g mph

Answer:
bumper cars colliding- inelastic
man jumping in a cab- perfectly inelastic
mud sticking to car - perfectly inelastic
hat being sat on door being slammed- inelastic
ball bouncing- elastic
Explanation:
In a perfectly inelastic collision, the objects stick together after collision and move with a common velocity. Maximum kinetic energy is lost during such collision.
For an inelastic collision, kinetic energy is partly lost and the colliding objects move apart at different velocities. This is often encountered in real life situations.
For an elastic collision, both momentum and kinetic energy are conserved. The object rebounds with the same relative velocity with which it approached.
