The angle theta of the spring is 31 degrees. To solve for this, show the equation which is equal to the 10lb ball. With this, the unknown will be the angle. Then transpose/transfer the terms in order to isolate the variable for the angle. First solve for s, then solve for angle theta. You will come up with s = .5849 ft and angle theta = 31.2629 or 31 degrees. Hope this helps.

Answer:
the curve inclination is increased so that a weight component helps keep the car on track
Explanation:
In the sledging competition these devices go at quite high speeds over 100 km/h, so when reaching the curves the friction force is not enough to keep the car on the track. For this reason, the curve inclination is increased so that a weight component helps keep the car on track.
In general we can solve Newton's second law for this case, with the condition of no friction, it is found that
V² = r g tan θ
Where V is the maximum velocity, r is the radius of the curve a, θ is the angle of the inclination
Answer:
Explanation:
The force that one atom exerts on the other is the negative derivative of the potential energy = 
F(x) = - 
( -C₆ / x⁷) = - (- (-6) C₆ x⁻⁶ ⁻¹) = - 6C₆ /x⁷
when xis negative, F is positive and when x is positive, F is negative. It is therefore and attractive force and F is always directed to the center
