The answer is -6a (my answer needs to be longer so I'm adding this)
Answer:
v = 39.2 m/s
Step-by-step explanation:
They gave you the equation for velocity during freefall in picture2 as:
v = 9.8t m/s
they ask you what the value of v (velocity) is after t=4 sec.
Just plug in t=4 into the equation.
v = 9.8t
v = 9.8(4)
v = 39.2 m/s
A. 48 b. 76 c. 91 d. 63.
c. would produce the largest answer
Answer:
the answer is minus four because the smaller number minus the greater one
P=42 m
1/2 of P=21
1/2 of P= l+w
21=13+8
A=13×8
A=104 m^2. As a result, the length is 13 m, and the width is 8 m. Hope it help!
