Step-by-step explanation:
Given that:
Distance between roof of the terminal and ground = 709 feet
A bucket was dropped from the roof.
To find:
The time taken by the bucket to hit the ground?
Solution:
Distance traveled, = 709 feet
Initial velocity of the bucket, = 0 feet/sec (because initially it was at rest)
Acceleration of the bucket will be equal to acceleration due to gravity i.e.
or 32.1741
Let the time taken is seconds.
Formula for distance is given as:

Answer:
The truck travel must to have a constant speed of
Step-by-step explanation:
we have
where
d expresses a car's distance in feet
t is the number of seconds
<em>Find the distance d for t=8 sec</em>
<em>Find the distance d for t=8.2 sec</em>
The total distance in this interval of 0.2 sec is
<em>Find the speed of the car</em>
Divide the total distance by the time
therefore
The truck travel must to have a constant speed of
