Answer:
200 N = 200 Newtons
Explanation:
Just use the formula F = m*a
F = Force in Newtons
m = mass and is 20 kg
a = acceleration and is 10 m/s^2
F = 20 * 10
F = 200 Newtons.
Answer: 3.63 km/s
Explanation:
The escape velocity equation for a craft launched from the Earth surface is:
Where:
is the escape velocity
is the Universal Gravitational constant
is the mass of the Earth
is the Earth's radius
However, in this situation the craft would be launched at a height 
over the Eart's surface with a space elevator. Hence, we have to add this height to the equation:
Finally:
