A football is kicked upward from a height of 6 feet with an initial speed of 70 feet per second. Use the formula to find the bal
Eddi Din [679]
70 ft per sec going upward 3 sec from 6 ft high should reach 216 ft, but unfortunately gravity is pulling it and at some point it starts to go backward (at 2.176 second), so to compensate the upward slowing down and distance dropped, use -32.176 times 3 square times 1/2 = -144.792 which is the natural drop distance if the football is released mid air without a initial speed after 3 seconds. 216 - 144.792 = 71.208 ft high.

A roll of 100 pennies is in the shape of a right cylinder. Each penny has a diameter of 0.75 inches and a thickness of 0.04 inch
zalisa [80]

Answer:

  • (B) π(0.75/2)²(4)

Step-by-step explanation:

<u>The volume formula:</u>

  • V = πr²h

<u>Given:</u>

  • d = 0.75 in ⇒ r = d/2 = 0.75/2 in
  • h = 0.04 in

<u>The volume of each penny:</u>

  • V = π(0.75/2)²(0.04)

<u>The volume of 100 pennies:</u>

  • V = 100*π(0.75/2)²(0.04) = π(0.75/2)²(4)

Correct choice is B
