1. A ball is thrown into the air with an initial x velocity of 15 m/s and an initial y velocity 10 m/s from an initial height of 20 m. a) What is the maximum height of the ball? How long does it take the ball to reach its maximum height? b) What is the range of the ball?

Time left 0:39:02 The Burj Khalifa is the tallest building in the world with a height of 0.828 km. On his delivery on Christmas Eve, Santa Claus accidentally bumps into the Burj Khalifa and drops a toy from the very top of the building. What is the magnitude of the velocity (in m/s) of the toy 0.018 km from above the ground? Neglect air resistance. 9 9.81m/8² Do NOT include units in your answer. Round your answer to 2 decimal places. Do NOT change to scientific notation. Ignore significant figures. Answer
