The magnitude of acceleration, is the same. You are probably thinking about centripetal force F=mv^2/r. But the question asks about the centripetal acceleration ac=v^2/r of the ride. The rides velocity and radius remains constant so the magnitude of acceleration of the ride is the same for both adult and child

Which equations are equivalent to 3/4+m=-7/4? Select three options.
Karo-lina-s [1.5K]

Answer:

M= -10/4

M = -5/2

-5/4 + m = -15/4

Explanation:

3/4 + m = -7/4

Subtract 3/4 from both sides

3/4 + m - 3/4 = -7/4 - 3/4

m = (-7-3) / 4

m = -10/4

m = -5/2

Check the options

11/4 + m = -1/4

m = -1/4 - 11/4

m = (-1-11) /4

m = -12/4

m = -3

-5/4 + m = -15/4

m = -15/4 + 5/4

m = (-15+5) /4

m = -10/4

m = -5/2
