in order to find the average velocity use change in Displacement / change in time?
Explanation:
Answer:
Va is two times greater than Vb
Explanation:
The maximum height reached by the balls are:

Since we are told that Ya = 4Yb:

Simplifying the equation:


Average velocity is a vector unit (i.e. includes magnitude <em>and </em>direction) calculated by working out distance ÷ time:
80 metres ÷ 20 seconds = 4 metres/seconds (m/s)
Therefore, your final answer is C. 4 m/s south.

where:
F - force
m - mass
a - acceleration
We transform this formula to get a:
