A ball moves on a smooth frictionless surface before entering a surface covered with grass. The speed of the ball at three different points is shown in the given figure. The relation among the speeds of the ball at the three given points is

• A.  \[{{v}_{1}}<{{v}_{2}}<{{v}_{3}}\]                             
• B.  \[{{v}_{1}}>{{v}_{2}}>{{v}_{3}}\]
• C.  \[{{v}_{1}}={{v}_{2}}>{{v}_{3}}\]                             
• D.  \[{{v}_{1}}={{v}_{2}}<{{v}_{3}}\]
