The normal force equals the magnitude of the gravitational force as a roller coaster car crosses the top of a 58-m-diameter loop
dedylja [7]

Answer:

16.87 m/s

Explanation:

To find the speed of the car at the top, when the normal force is equal the gravitational force, we just need to equate both forces:

N = P

m*a_c = mg

a_c is the centripetal acceleration in the loop:

a_c = v^2/r

So we have that:

mv^2/r = mg

v^2/r = g

v^2 = gr

v = \sqrt{gr}

So, using the gravity = 9.81 m/s^2 and the radius = 29 meters, we have:

v = \sqrt{9.81 * 29}

v = \sqrt{284.49} = 16.87\ m/s

The speed of the car is 16.87 m/s at the top.
