As you said it was dropped so in that case I'll take 78.4 meters as the height..
we know that
h = ut + 0.5*g*t(sqr)
t(sqr) = 78.4/(0.5*9.8) [g = 9.8 ms-2]
t = √16
t = 4
So it'd take 4 seconds
The answer to the questions
The top right “double sided” i’m pretty sure
Answer:
16
Step-by-step explanation:
v=lwh
v=4x2x2
If it is in decimal form then multiply the number by 100
Ex: .36
Multiply by 100
.36 x 100 = 36 so 36%
