A ball is thrown upward from the surface of Mars with an initial velocity of 50 feet per second. The height of the ball can be modeled by h(t)= -6.5t^2+50t (must show work)

a)What is the maximum height the ball reaches?

b) How long does it take the ball to fall back to the surface of Mars?

c) How long is the ball above 50 feet?

d

step-by-step explanation:

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
