<span>1. h = -16t² + vt + c
⇒ vt = 16t² + h - c
⇒ v = 16t + (h-c)/t
2. c = 5 ft
t = 3s
h = 131 ft
v = 16*3 + (131-5)/3 = 48 + 42 = 90 ft/s
when t=0, velocity is not defined. That means at t=0, there is no velocity of the t-shirt or it is 0.

Answer:
its a
Step-by-step explanation:
6(7+5) + 3
Hope this helps :)
To check:
PEMDAS
7+5 is 12
6(12) + 3
72 + 3
75
