Answer:
• Its acceleration is zero
Explanation:
from definition of acceleration:
• since velocity is constant, change in velocity is zero
• therefore:
The SI unit of power is???

Answer:
The normal force is 85,42 N
Explanation:
There is no friction force, therefore there is no relationship between the normal force and the friction.
We can find the normal force using a free body diagram and check the forces that are acting on the sled. The total forces are equal to 0 because there is no movement in the y-axis. The movement exists only on the x-axis.
