The change of velocity is from 18.5 to 46.1 m/s or 46.1 - 18.5 = 27.6 m/s. The time of change is 2.47 s. So the acceleration is 27.6 m/s / 2.47 s = 11.17 m/s^2. The distance traveled is average velocity times time of travel.
Stationary at rest or moving with constant motion
Explanation:
If the force acting upon an object are balanced, the object must be stationary or at rest or moving with constant velocity.
According to newton's first law of motion;
"An object will remain in its state of rest or of uniform motion unless acted upon by an external force".
This suggests that body at rest has balanced forces acting upon it.

Kinetic energy is energy in motion and potential energy is energy that is stored.
Answer:
393.75J
Explanation:
The potential energy stored in a spring is given by the formula:
E = (k•x²)/2 where E is the energy, k is the spring constant and x is the stretched distance, so:
E = (350•1.5²)/2 = 393.75J
