gYou throw a ball vertically upward so that it leaves the ground with velocity 5.40 m/s.(a) What is its velocity when it reaches its maximum altitude

Explanation:

Given

--- Initial velocity

Required

Determine the velocity at maximum altitude

When a ball or an object is thrown upward, it reaches a maximum height, then stops momentarily and then descends downwards

The sequence of the event is:

At the point where the object stops (i.e. the maximum altitude), the velocity is 0

Hence, the required velocity is:

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
