2*) In the long jump, an athlete launches herself at an angle above the ground and lands at the same height, trying to travel the greatest horizontal distance. Suppose that on earth she is in the air for time T, reaches a maximum height h and achieves a horizontal distance D. If she jumped in exactly the same way during a competition on Mars, where g.mars = 0.379 of its earth value, find her time in the air, maximum height and horizontal distance. Express each of these quantities in terms of its earth value. Air resistance should be neglected on both planets. (t = 2.64 TẸ, h = 2.64 hg, D = 2.64 Dp)

Problem 1: The Lunar Roving Vehicle used in NASA's late Apollo missions reached an unofficial lunar land speed of 5.00 m/s. Suppose, while traveling at that speed, it hit a bump that launched it at an angle of 24.4 degrees above the horizontal lunar surface. How long, in seconds, would the vehicle be off the ground? The acceleration of gravity on the Moon has a value of 1.62 m/s2. Numeric : A numeric value is expected and not an expression. t =
