Projectile Motion – Numerical Problems (Assignment for KV Pattom Class XI students)

  1. A football player kick a ball at an angle of 37° to the horizontal with an initial speed of 15 m/s. Assuming that the ball travels in a vertical plane, calculate (i) the time at which the ball reaches the highest point. (ii) the maximum height reached by the ball (iii) the horizontal range of the projectile and (iv) the time for which the ball is in air.
  2. A body is projected with a velocity of 20…

Learning is a process of acquiring and stabilizing of successful or rewarded responses and of eliminating the unsuccessful or unrewarded responses.
