Question
ltem 11 Part A A projectile is fired from a very powerful cannon vertically upward from Earth's surface at an initial speed of 5.1 km/s. Assume that air resistance is negligible. What is its maximum altitude above the ground? The answer is the maximum height above the ground, not the maximum distance from the center of the earth. Assume that air resistance is negligible. The mass of the earth is 5.97E24 kg and the radius of the earth is 6370 km. Express your answer using two significant figures. A2 Submit My Answers Give UpExplanation / Answer
here,
the initial speed , u = 5.1 km/s = 5100 m/s
a)
the maximum altitude above the ground , h = u^2 /2g
h = 5100^2 /(2 * 9.81)
h = 1.3 * 10^6 m
