Answer and Explanation:
Data provided in the question
Carbon mass = m
Initial speed = v_i
Coefficient = μk
Based on the above information, the expressions are as follows
a. By using the energy considerations the expression for the carton moving distance is
As we know that
where,
b. The initial speed of the carton if the factor of 3 risen, so the expression is
1. B
2. A
3. B
4. C
5. heterogeneous
6. element
7. do
8. true

Answer:
is a field force, as gravity does not physically apply force and does not require proximity.
Explanation:
20N•m or 20J. Work is equal to force•distance, and 5N•4m is 20N•m, or J
