9.8)(0)+1/2Vi^2=(9.8)(100)+1/2(72)^2 solve for vi please show steps
Changed your "Vi" variable to just "V"
Solve for V:
V^2/2+0. = 3572.
V^2/2+0. = V^2/2 and 3572. = 3572:
V^2/2 = 3572
Multiply both sides by 2:
V^2 = 7144
Take the square root of both sides:
Answer: | V = 2 sqrt(1786) or V = -2 sqrt(1786)
