Concept explainers
The time of supplies before the plane is over head.
Answer to Problem 27P
5.6 sec.
Explanation of Solution
Given:
The distance between plane and land is 160 m and speed of plane is 180 km/hr.
Formula Used:
Displacement
Calculation:
Distance, y = − 160 m
Speed, v = 180 km/hr.
Acceleration due to gravity g = 10 m/s2
Initial velocity, u = 0 m/s Substituting the values
Conclusion:
Thus, time of supplies before the plane is overhead is 5.6 sec.
