The final velocity of the other student after the elastic collision with Logan is 6.94 m/s.
<h3>
Conservation of linear momentum</h3>
The final velocity of the other student will be determined by applying the principle of conservation of linear momentum for elastic collision.
- let u represent initial velocity
- let v represent final velocity
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
Substitute the given parameters and solve for final velocity of the other stsudent.
74(7.6) + 81(0) = 74(0) + 81(v₂)
562.4 = 81v₂
v₂ = 562.4/81
v₂ = 6.94 m/s
Thus, the final velocity of the other student after the elastic collision with Logan is 6.94 m/s.

The energy that the student shoud use in order to climb the stairs is equal to its increase in gravitational potential energy:
where m is the mass of the student, g the gravitational acceleration and
the variation of height. Plugging numbers into the equation, we find
The power required for the student to climb the stairs is equal to the work done divided by the time taken:
"Reflection" is the change direction of waves when blocked by obstacle
