To solve this problem it is necessary to apply the concepts related to Newton's second law and the kinematic equations of movement description.
Newton's second law is defined as
Where,
m = mass
a = acceleration
From this equation we can figure the acceleration out, then
From the cinematic equations of motion we know that
Where,
Final velocity
Initial velocity
a = acceleration
x = displacement
There is not Final velocity and the acceleration is equal to the gravity, then
From the equation of motion where acceleration is equal to the velocity in function of time we have
Therefore the time required is 0.0705s
Answer:
Divide the change in velocity by the time interval
Explanation:
Acceleration is defined as the rate of change of velocity.
mathematically it is the change in velocity divided by the time taken for that change.
i.e Divide the change in velocity by the time interval.
Answer:
improve cardiorespiratory endurance
In general, there are three main states of matter that we encounter everyday. These are named solid, liquid and gas. It is a gaseous state that consists of atomic particles that move independently and interact only weakly with surrounding neighbours. An example of a gas within our atmosphere is oxygen.
