Given

--- Height

Solving (a): The initial speed

To do this, we make use of the third equation of motion

In this case:

--- final velocity at the maximum height

Convert height to metres

Substitute these values in

Collect Like Terms

Take the positive square root of both sides

--- approximated

Hence, the initial velocity is 4.56m/s

Solving (b): Time spent in the air.

This will be solved using the first equation of motion.

Where:

--- final velocity at the maximum height

So, we have:

Collect Like Terms

Make t the subject

--- approximated

The above is the time it reaches the maximum height.

The time it stays in the air is:

This gives:

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;
