Homework Statement
An extreme amusement park ride accelerates its riders upward from rest at 50.0 m/s in 7 seconds. Ignoring air resistance, what average upward force does the seat exert on a rider who weights 1120N?
t = 7.00s
v = 50.0 m/s
Mass = 114.285
mg = 1120N
Homework Equations
∑F= ma
The Attempt at a Solution
I am not sure of that v is vi or vf.
I know my first step needs to be to solve for acceleration I just do not know how to do it given the information that I have.
Thanks
