Explanation:
Gravitational Potential Energy at earth surface
Gravitational Potential Energy at height h is
Energy required to lift the satellite
Now Energy required to orbit around the earth
(given)
(b)For greater height is greater than
thus energy to lift the satellite is more than orbiting around earth
Answer:
a)
b)
c)
Explanation:
From the exercise we know the initial velocity of the projectile and its initial height
To find what time does it take to reach maximum height we need to find how high will it go
b) We can calculate its initial height using the following formula
Knowing that its velocity is zero at its maximum height
So, the projectile goes 1024 ft high
a) From the equation of height we calculate how long does it take to reach maximum point
Solving the quadratic equation
So, the projectile reach maximum point at t=2s
c) We can calculate the final velocity by using the following formula:
Since the projectile is going down the velocity at the instant it reaches the ground is:
