Erosion is caused naturally by water, wind or gravity, and accelerated erosion is caused by human use of land.
Output can not be greater than input because the conversion of energy can not be greater than 100%.
The net force will point towards the acceleration of the object, as supported by Newton's second law.

This is important so everyone knows what they should be doing
Answer:
-1.5m/s²
Explanation:
Acceleration can be thought of as [Change in Velocity]/[Change in time]. To find these changes, you simply subtract the initial quantity from the final quantity.
So for this question you have:
- V_i = 110m/s
- V_f = 80m/s
- t_i = 0s
- t_f = 20s
which means that the acceleration = (80-110)/(20-0)[m/s²] = (-30/20)m/s² = -1.5m/s²
