Answer:
Explanation:
From work energy theorem
Work done by all forces = Change in kinetic energy
Lets take
m= mass of object
h=height from the ground surface
initial velocity of object = 0 m/s
The final velocity of object is v
Work done by gravitational force = m g . h
The final kinetic energy = 1/2 m v²
So
Work done by all forces = Change in kinetic energy
m g h = 1/2 m v² - 0
v² = 2 g h

whats the question... you didn't put the question up
Answer:
Force = 150 Newton.
Explanation:
Given the following data;
Mass = 60kg
Acceleration = 2.5m/s²
To find the force;
Force = mass * acceleration
Force = 60 * 2.5
Force = 150 Newton.
Therefore, the force required to accelerate this mass is 150 Newton.
The moon is thought to have an iron-rich core whose radius
is 330 km, plus or minus an uncertainty of 20 km.
That puts its diameter in the range of 620 km to 700 km.
