Homework Statement
A 1200 kg car has a speed of 5 m/s at the top of a circular ramp of 10 m in radius. The normal force exerted by the seat of the ramp on the car is :
A) 9000N B) 9600 N C)11250 N D)13650 N E)14150 N
Homework Equations
∑F=ma
ac = m v^2 /r
The Attempt at a Solution
I tried to answer this question but the problem is I don't know where I made the mistake. This is my tried :
∑F = ma = m v^2 /r = N - mg
N = 1200 * 5^2 / 10 + 1200*10
N = 15000 N
So can you check please if it's correct or not ?
Thank you.
