B R In a playing field, a girl at position A throws a ball with an initial velocity of v, = 15 m/s, and an angle of 0 50° from the horizontal plane. A boy wishes to catch the ball at the same height at which it was thrown. The achieve this, the bọy runs backward to position B with a constant speed of vg 3.24 m/s to catch the ball at a sufficient distance. a. Compute the total distance R between the boy and the girl when he catches the ball at B. b. Calculate the magnitude of relative velocity and relative acceleration of the ball with respect to the boy at the instant he catches the ball.
