(a)
To show: The value of e is 1 for a perfectly elastic collision and
(a)
Explanation of Solution
Given:
For a perfectly elastic collision, kinetic energy is conserved before and after the collision that is
Formula Used:
Calculation:
Substitute the condition for perfectly elastic collision in the formula of co-efficient of restitution.
Now, substitute the condition for completely inelastic collision in the formula of co-efficient of restitution.
Conclusion:
Hence, for a perfectly elastic collision
(b)
A formula for
(b)
Answer to Problem 37P
Explanation of Solution
Given:
An object is dropped onto a heavy steel plate, as shown in the figure.
As seen in the figure, heavy steel plate will remain stationary before and after the collision. So,
Formula Used:
During falling or rising, energy is conserved that is kinetic Energy is converted into Potential Energy and vice versa.
Calculation:
For falling on the steel plate, velocity will be positive
For moving up after bouncing from the steel plate, velocity will be negative
Now, substituting both of these velocities in the formula to calculate the co-efficient of restitution, we get
Conclusion:
Hence, formula for
