Question
In a vertical plane, a smooth horizontal straight track is tangential to a smooth semicircular track of radius R at point B. A small ball, treated as a particle, moves from point A on the horizontal track and enters the semicircular track at point B. The ball just passes through the highest point M of the semicircle and flies off horizontally from M. Neglect air resistance.
Which of the following statements is INCORRECT?
Options
A
The speed of the ball at point M is
B
The speed of the ball at point A is
C
The horizontal distance between point B and the landing point of the ball is 2R
D
The kinetic energy of the ball upon landing is
