s to questions: i) How does gravity affect the motion of the object in the horizontal direction? ii) What is the vertical component of the velocity of the object at the peak height? iii) Are the velocities of the object in the x and y directions dependent on each other. Explain? iv) If there was air resistance operating against the ball in the x- direction, how would it affect the velocity and acceleration in the x-direction? v) If you used two balls of masses 10 grams and 20 grams respectively, how would mass affect their motions in the x and y directions? Explain
