Since direction is part of velocity, and the object is moving in a circle, its velocity is constantly changing.
Answer:
The escape speed for the craft is 1.49 m/s.
Explanation:
In this case we need to find the escape speed for a craft launched from a space elevator at a height of 56,000 km. The escape velocity is given by :
Here,
G is universal gravitational constant
M is mass of earth
d = r + h, r is radius of Earth
So, the escape speed for the craft is 1.49 m/s.
