3. You are watching a fancy celebration which includes fireworks. Theseare shot from a movable platform standing at a height of 30 m aboveground. They are shot straight upwards, and reach a maximum altitudeof 150 m from the platform. Accidentally, one of the fireworks does notexplode and falls back to the ground, nearly missing the platform.You can assume the trajectory to be perfectly vertical. You may ignoreair resistance. Take the magnitude of g to be 9.8 m/s².a. Draw a sketch of the situation, labeling the height of the platform, theinitial velocity of the maximum elevation of the firework, the(unknown) initial velocity of the firework, and the (unknown) velocityof the firework just before it hits the ground.b. What is the velocity of the firework at the peak of its trajectory?c. How long does it take the firework to reach the peak of its trajectory?d. What is the initial velocity of the firework?e. What is the total time that the firework spends in the air?f. What is the velocity of the firework (magnitude and direction) as it hitsthe ground?g. Prove that the following equation is true for a linear motion withconstant acceleration. v² =+2a(s-50)Hint: You can derive it from two other well known equations.
