A ball rolls without friction from the top of a 40° inclined plane. Initially, the ball is released from a height h₁ = 10 meters; at height h₂ = 7 m the inclined plane is covered in ice all the way to the bottom so the ball slides on ice. What is the velocity of the ball as it reaches the end of the inclined plane? Consider the ball is equivalent with a thin wall sphere and g = 9.80 m/s²

A ball rolls without friction from the top of a \( 40^{\circ} \) inclined plane. Initially, the ball is released from a height \( h_{1}=10 \) meters; at height \( h_{2}=7 \mathrm{~m} \) the inclined plane is covered in ice all the way to the bottom so the ball slides on ice. What is the velocity of the ball as it reaches the end of the inclined plane? Consider the ball is equivalent with a thin wall sphere and \( \mathrm{g}=9.80 \mathrm{~m} / \mathrm{s}^{2} \). Select one: a. \( 13.1 \mathrm{~m} / \mathrm{s} \) b. \( 14.2 \mathrm{~m} / \mathrm{s} \) C. \( 17.3 \mathrm{~m} / \mathrm{s} \) d. \( 22.2 \mathrm{~m} / \mathrm{s} \)
