Answer:
An X-ray is used to take pictures of your bones. The waves that are used are known as radiation waves.
Stopped at the end of the tracks by a spg-damper system, as shown in fig. 1
For any object thrown upwards where only the force of gravity is acting upon it, uses the following formula for the maximum height attained.
H= v²/2g, where g = 9.81 m/s²
There are two information of velocities are given. However, we use the 20 m/s information because this is the launch velocity. Hence, the solution is as follows:
H = (20 m/s)²/2(9.81 m/s²)
<em>H = 20.4 m</em>
