To Find: The number of poles.
Answer to Problem 60GP
2
Explanation of Solution
Given info:
Height,
Speed of truck,
Distance between the poles,
Height of the bed of the truck,
Acceleration due to gravity,
Initial speed of the agent bond,
Formula used:
Second equation of kinematics:
Where,
Calculation:
Distance fall by the agent bond,
Let falling time of agent bond be
Form kinematics equation:
Time taken by truck to cross two successive poles:
Since, agent bond takes 1.46 s, therefore truck should be two poles away when he jumps down from bridge onto truck.
Conclusion:
Hence, number of poles are 2.
