Answer:

Explanation:
Given:
- actual weight on the earth, m = 150 lbs × g = 68.0389 kgf
- apparent weight in the spacecraft, M = 175 lbs × g = 79.3787 kgf
∵The apparent weight increases it means that the spacecraft is accelerating in the direction opposite to the gravity and having the value greater than 9.8
DIfference in the weight,



This difference in weight is due to the difference in acceleration of the gravity and the spacecraft.
So, the quantity of acceleration responsible for this difference in weight:
.................(1)
where:
m= mass of the body being accelerated
= difference in the acceleration
from eq. (1)


∴The actual accelerationof the spacecraft:
a=
a = 9.8 + 1.6333
a = 
Ans: Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object. The classic example of potential energy is to pick up a brick.
