A acceleration in our case gravity 9 8 m s 2 v starting velocity zero since it is being dropped not thrown h starting height the number we don t know d ending height zero since it hits the ground t time the ball has traveled 3 1 seconds we plug all these numbers in.
Of 8 balls dropped from the peak of the roof.
Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
Ball 1 is dropped zero initial velocity.
The total run is the distance from the peak to the edge of the roof which in this case is the total width divided in half which is equal to 10 feet or 120 inches.
Calculus q a library ight of the ball above the ground in feet 8.
Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10.
Since the fourth drop is dropped at the instant the first drop reached the ground the time that elapsed is equal to the time for three drops to have been released.
The length of the roof is 69 5 m and the angle of the roof is 18 0 below horizontal.
A worker on the roof lets go of a hammer from the peak of the roof.
Define variables to represent the values of the varying quantities in this situation.
A ball is dropped off of the roof of a building.
If the first drop was released at time 0 the fourth was then released at time 3t as you correctly deduced.
