(a)
The time taken to fall down straight from the building.
(a)
Answer to Problem 35P
8.8 seconds.
Explanation of Solution
Given:
Initial velocity
Time taken to fall
Acceleration experienced is acceleration due to gravity
Height of building
Initial position at the top of building
Final position at the bottom of building
Formula Used:
Kinematics equation that relates initial position, final position, initial velocity, acceleration and time of an object is given as
Calculation:
Substituting the values
Conclusion:
Therefore, time of fall is 8.806 seconds.
(b)
The velocity just before landing
(b)
Answer to Problem 35P
Velocity just before landing is
Explanation of Solution
Given:
Initial velocity
Time taken to fall
Acceleration experienced is acceleration due to gravity
Height of building
Initial position at the top of building
Final position at the bottom of building
Formula Used:
Acceleration of an object is given as
Calculation:
Substituting the values to find the acceleration.
Negative sign indicates the downward direction.
Conclusion:
Therefore, velocity just before landing is
