- Don’t answer these questions. Instead, draw a picture of the situation. Give names and labels to important pieces. Assign values to important pieces. Come up with an equation that relates pieces of the situation that might be helpful when answering the question. Don’t solve anything.2) A person is standing 350 ???? away from a model rocket that is fired straight up into the air at a rate of 15 ??/???. At what rate is the distance between the person and the rocket increasing 20 ??????? after liftoffKayla throws a soccer ball out of her dorm window to Hafsa, who is waiting below to catch it. Kayla throws the ball at an angle of 40° below horizontal with a speed of 1.2 m/s, and Hafsa catches it 2.4 s later. How far from the base of the dorm does Hafsa stand to catch the ball, in meters? Use g = 10.0 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.You hit a golf ball into the air with an initial horizontal speed of 40 m/s and an initial vertical upward speed of 50 m/s. Ignore air resistance and use g = 10 m/s2. How much time does it take for the ball to reach its maximum vertical displacement? What is the maximum vertical displacement of the ball? What is the horizontal displacement of the ball when the ball is at its maximum vertical displacement?
