Answer:
The average velocity of the sled is vavg = s/t.
Explanation:
Hi there!
The average velocity is calculated as the traveled distance over time:
vavg = Δx/Δt
Where:
vavg = average velocity.
Δx = traveled distance.
Δt = elapsed time.
We already know the traveled distance (s) and also know the time it takes the sled to travel that distance (t). Then, the average velocity can be calculated as follows:
vavg = s/t
Have a nice day!
The physical changes are you are breaking down the food u eat and the chemical changes are when the enzymes in your stomach break down the food that you have already eaten
Answer:
0.25
Explanation:
Friction force is the normal force times the coefficient of friction.
F = Nμ
50 N = (200 N) μ
μ = 0.25
The relationship between mass and acceleration is an inverse proportionality
Explanation:
The relationship between the acceleration of an object and its mass is given by Newton's second law, which states that:
where
F is the net force on the object
m is its mass
a is its acceleration
From the equation, we notice that if the force on the object is kept constant, then the mass and the acceleration are inversely proportional to each other. This means that:
- If the mass of the object is increased, its acceleration will decrease
- If the mass of the object is decreased, its acceleration will increase

Average speed = total distance / total time.
That's 172 km / 5 hr = 34.4 km//hr
