Number 79 physics
the velocity of the ball

  (a)  16 ft/s

  (b)  1.5 s

Step-by-step explanation:

(a) Put 1 where t is in the expression and do the arithmetic:

  -32×1 +48 = 16 . . . . feet per second

__

(b) Use the hint and solve for t:

  -32t +48 = 0

  t -1.5 = 0 . . . . . divide by 32

  t = 1.5 . . . . . . . . add 1.5

The ball reaches its maximum height after 1.5 seconds.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
