Arrange the change in kinetic energy in the decreasing order.
Answer to Problem 49P
The decreasing order of change in kinetic energy is
Explanation of Solution
Write the expression for conservation of energy
Here,
Rearrange (I)
Write the expression for change in kinetic energy
Here,
Write the expression for
Here,
Substitute (III) in (II)
(a)Substitute
Thus, the change in kinetic energy in (a) is
(b)Substitute
Thus, the change in kinetic energy in (b) is
(c)Substitute
Thus, the change in kinetic energy in (c) is
(d)Substitute
Thus, the change in kinetic energy in (d) is
(e)Substitute
Thus, the change in kinetic energy in (e) is
(e)Substitute
Thus, the change in kinetic energy in (f) is
Thus, the decreasing order of change in kinetic energy is
