A boy throws a ball at an angle 45o with the horizontal at t = 0 at origin. Path of the ball follows the trajectory y = x – 5x2. The boy start running with a constant velocity 1 m/s along x-axis at t = 0. Take g = 10 m/s2. Choose correct option/s. (a) Boy and ball are in same vertical line at each instant of time. (b) At t = 0.1 s, velocity of ball w.r.t. boy = zero. (c) At t = 0.2 s, ball hits boy. (d) Ball never hits boy. These kind of quality questions are available at http://www.vidyadrishti.com/login.php . Questions are highly conceptual and well researched. New innovative questions framed by IITians. You will find new questions (just as in IIT-JEE). Rate me if found useful.
