The answer would be 2. To find it, you do 8 - 3 - 3 = 2.
Step-by-step explanation:
b) average velocity : ∆x/∆t = 100/9.8 ≈ 10.204 m/s
c) ∆x = v.∆t = 10.204 × 3 = 30.612 m
d) ∆t = ∆x/v = 80/10.204 = 7.84 s
Answer:
a) 3
b) -3
Step-by-step explanation:
Absolute value makes sure that whatever is in the lines will equal a positive.
