1 answer:
Ulleksa [173]3 years ago
8 0

Answer:

A) 11.25 m

B) 3.4s

C) 0.75

Step-by-step explanation:

A) Put in given time. Then, y = 11.25m

B) If the object is at ground, then y = 0.

So,  0 = 17t - 5t^2   => t = 0 or 3.4 [ 0s is initial height, so it's not valid ]

C) H1 = 17*(1.5+1) - 5*((1.5+1)^2) = 11.25

H2 = 17*1 - 5*(1^2) = 12

H2 - H1 = 0.75
