Answer:
increasing more mass will decrease the acceleration of the skateboarder.
Explanation:
Newton's Second Law states whenever an unbalanced force is applied on an object, it produces an acceleration in the object in the direction of force. This acceleration is directly proportional to force by inversely proportional to mass.
where,
F = Force
a = acceleration
m = mass
If we consider force applied on the skateboarder, then the acceleration is inversely proportional to mass, only.
<u></u>
<u>Therefore, increasing more mass will decrease the acceleration of the skateboarder.</u>
Answer:
The average force exerted on the pier is N
Explanation:
Given :
Mass of ship Kg
Distance m
Velocity
Now find the average velocity,
Now find the time taken by ship to travel 4.44 m.
sec
Now calculating average force,
Where = 0.652
N
Therefore, the average force exerted on the pier is N
