A tennis ball rolls off of the roof of a building (8.1 m) with a speed of 4 m/s. It lands on a frictionless bench 7.6 m below and rolls along that for 2 s before rolling off and falling to
the ground. How long did the ball take to fall from the roof to the ground? What was the
range of the ball? What was the ball's final velocity when it hits the ground?

Step-by-step explanation:

divide up your information into two A ball rolls off a 1.0 m high table and lands on the floor, 3.0 m away from the A carpenter tosses a shingle off a 9.4 m high roof, giving it an initial horizontal A tiger leaps horizontally from a 12 m high rock with a speed of 4.5 m/s.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
