Banking angle is the angle between the normal horizontal path (N) and the curved banked path. The angle of banking of a curved path is defined as the angle through which the outer edge of the road is raised over the inner edge.

It is calculated as:

tan\theta = \frac{v^2}{rg}

Here,

v = Linear velocity of object

r = Radius of the curved path

a_c = Acceleration due to gravity

Rewriting the equation to solve for the radius we have that

r=\frac{v^2}{gtan\theta}

r = \frac{30}{(9.8)(tan 75\°)}

r = 24.6m

Therefore the radius of a bobsled turn banked at 75° taken at 30m/s is 24.6m

Hello,help me with this out please i need it hurry but please ensure your answer is correct..I attach here with my question.

Answer:

.409 N

Explanation:

For this to balance, the moments around the fulcrum must sum to zero.

On the left you have   .21   ( is that down? I will assume it is)

      Counterclockwise moments :

        .21 * 40     +  1.0 * 20    

     Clockwise moments :

        .5 * 20     +     F * 45

these moments must equal each other

.21*40 + 1 *20   =  .5 * 20 + F * 45

   F = .409 N

What should a free-body diagram look like for a skydiver who has opened his parachute and is now slowing down as he falls?
mote1985 [20]
The last choice. Two arrows and the arrow up is shorter than the arrow down. Since the guy is falling and he’s opened his chute, he’s slowing down but he’s still falling meaning the force of gravity is stronger than the air resistance.
