You are studying and you need to try and find an answer this numerical yourself


Am sorry for being blunt but do it yourself. Read your book and try.

(NB: By x^2, I mean square of x)


These are the formulas that will help you for each part of the questions:

1. v^2 - u^2 = 2as

s = height =? v = final velocity = 0, u initial velocity = 22, a = acceleration = -g

Now you can find s

2. v = u + at

v = final velocity = 0, u = 22, a = -g

This will give you value of time t

3. v = u + at

u = 22, a = -g, t = 1.5

4. v^2 - u^2 = 2as

u = 22, a = -g, s = 10
