To compute: - The rank of the five-clay potsaccording to their speed when they strike to the ground from least to greatest.
Answer to Problem 96A
Explanation of Solution
Given info:
Height from the ground,
Acceleration due to gravity,
(A)1 kg dropped from rest with initial velocity,
(B)1 kg thrown downward with initial velocity,
(C)1 kg thrown upward with initial velocity,
(D)1 kg thrown horizontally with initial velocity,
(E)2 kg dropped from rest,
Formula used:
For motion in straight line with constant acceleration
Mathematically it can be represented as,
Where,
Calculation:
Case A:
Clay is moving downward, therefore acceleration:
Using the formula of kinematics equation:
Case (B):
Clay pot is moving downward, therefore acceleration:
Using the formula of kinematics equation:
Case (C):
Let height reached by clay pot above the rooftop be
Therefore, formula of maximum height reached by projectile:
Plugging in the given values:
Total distance covered by pot from height
Using the formula of kinematics equation:
Case (D):
Since, pot thrown horizontally, therefore:
Maximum horizontal distance covered by pot is the range of pot,
Using the formula of kinematics equation:
Case (E):
Using the formula of kinematics equation:
Conclusion:
The rank of the speed:
