A ball is thrown vertically upward by a cricket player with an initial velocity of 40 m/s. if motion of ball accelerated by 10 m/s^2, then calculate 1) the maximum height reached by the ball
2) the distance covered by the ball when it reaches the player's hand
3) the displacement covered by the ball when it reached player's hand

A2 µc charge q1 and a 2 µc charge q2 are 0.3 m from the x-axis. a 4 µc charge q3 is 0.4 m from the y-axis. the distances d13 and d23 are 0.5 m. find the magnitude and direction of the resulting vector r. round your answer to the nearest tenth.
