Answer: A) The magnitude and direction of the acceleration change.
Explanation:
Because the force of the wall pushing on her increases.
According to Newton's third law of motion, to every action there is an equal and opposite reaction. When the Kamala pushes the wall, the wall also pushes her. Pushing harder against the wall causes the force of the wall pushing her also increase. Thus, making her roll faster.
Answer:
The solution is given below:
Explanation:
The computation of the speed is shown below
As we know that
Speed = distance ÷ time
where
distance is 2000 km
And, the time is 2.5 hours
SO, the speed is
= 2,000 ÷ 2.5
= 800 km/h
Now the distance would be the same i.e. 2,000 km
but the time is 2 hours
So, the speed is
= 2,000 km ÷ 2 hours
= 1,000 km/hr
The direction should be opposite to the first airplane
Some social patterns are helpful, while others are harmful.
