Answer:
3.53m/s²
Given:
- Mass of the person (m) = 65 kg
- Mass of the sled (m)= 20 kg
- Total mass = m + m(sled) = 65kg + 20kg = 85kg
- Net force (F)= 300 N
Using the formula above, we can calculate the acceleration of the person and the sled system:
a = 300N
————
85kg
a = 3.53m/s²
Therefore, the acceleration of the person and the 20 kg sled, when pushed with a force of 300 N, will be 3.53m/s²
