It seems like there may be a misunderstanding of the problem here. The question is asking for the value of h, which is the hit point above the center of the ball, in order for the ball to roll without slipping with a speed of 14.10 m/s. This means that the ball will be rolling and not sliding on the table. The initial velocity given (V0=15.0 m/s) is not relevant for this part of the problem.
To solve this problem, we can use the equation for rolling motion without slipping: V=ωR, where V is the linear velocity of the ball, ω is the angular velocity, and R is the radius of the ball. We also know that the kinetic coefficient (μ) between the ball and the table is 0.214.
First, we can find the angular velocity of the ball at a speed of 14.10 m/s by rearranging the equation: ω=V/R. Plugging in the values, we get ω=14.10 m/s ÷ 0.07 m = 201.43 rad/s.
Next, we can use the definition of kinetic coefficient to find the frictional force (F) acting on the ball: F=μmg, where m is the mass of the ball and g is the acceleration due to gravity. We can find the mass of the ball by using the formula for the volume of a sphere: V=4/3πR³. Plugging in the values, we get m=4/3π(0.07 m)³ρ, where ρ is the density of the ball. We can assume a density of 1 g/cm³ for a billiard ball, so m=0.229 kg. Plugging this into the equation for frictional force, we get F=0.214(0.229 kg)(9.8 m/s²)=0.48 N.
Finally, we can use the definition of torque (τ) to find the distance h: τ=FR, where R is the radius of the ball. Plugging in the values, we get τ=0.48 N(0.07 m)=0.0336 Nm. We also know that τ=Iα, where I is the moment of inertia of the ball and α is the angular acceleration. The moment of inertia for a solid sphere is 2/5MR², so I
