Task VI Sami made a bet with his friend Ahmad if he could shoot and break an empty bottle thrown by Ahmad using his catapult after 2 seconds from throwing the bottle. If Sami shoots a stone from his catapult at the same instant of throwing the bottle by Ahmad (t=0s) with initial velocity vi and angle with respect to horizontal. Ahmad who stand on 40 m apart on the ground level throws the bottle with initial velocity of 15 m/s and with angle 60° with respect to horizontal. Suppose that Ahmad tall is 135 cm and Sami tall is 140 cm Assume that: a. Air resistance effect is negligible. b. The motion of the stone and the bottle is Projectile Motion (2D) c. Use g = -9.8m/s2 d. Suppose that y=0 at the ground level and up the ground y is positive. Answer the following: A. Find the value of the velocity and angle that should Sami use to win the bet? B. What is the horizontal distance of the stone and the bottle at the instant of collision? C. What is the vertical distance of the stone and the bottle at the instant of collision?
