2. A rocket is launched directly upwards at sea-level and a viewer watches from 6500 meters away, also at sea-level. After some time, the viewer was able to measure the angle between the ground and the rocket as 75°. Use a sum or difference identity to help determine the height of the rocket at that time. Your answer should not have any trigonometric expressions or radicals in denominators 2. A rocket is launched directly upwards at sea-level and a viewer...
A Rocket launches the summit of a mountain on some planet which has a constant acceleration of −3.5 m/s2 . If the projectile maximum height of 925.75 m above sea level at t = 7 seconds, how high is the mountain and when will the projectile reach sea level? Include correct units and be accurate to two decimal places
