Answer:
continually change by the same amount each second
Explanation:
We all are aware with the fact that a car speeds is increased when we put our feet on the accelerator. The rate at which the particle's velocity change with time is called its acceleration. If the particle's velocity changes with constant rate, then its rate is called the constant acceleration.
Since the basic units are meter and seconds. And the SI unit of velocity is and acceleration's SI unit is
For example if the velocity is change from 2 to 4 m/s in 1 sec its acceleration is and again its velocity is change with 4 m/s to 6 m/s will again give constant acceleration in 1 s is
.
Answer:
9 meters
Explanation:
Given:
Mass of Avi is,
Spring constant is,
Compression in the spring is,
Let the maximum height reached be 'h' m.
Now, as the spring is compressed, there is elastic potential energy stored in the spring. This elastic potential energy is transferred to Avi in the form of gravitational potential energy.
So, by law of conservation of energy, decrease in elastic potential energy is equal to increase in gravitational potential energy.
Decrease in elastic potential energy is given as:
Now, increase in gravitational potential energy is given as:
Now, increase in gravitational potential energy is equal decrease in elastic potential energy. Therefore,
Therefore, Avi will reach a maximum height of 9 meters.
