Question

Q4. A ball is thrown straight up, from 3 m above the ground, with a velocity of 14 m/s.
Gravity pulls it down, changing its position by about 5 m per second squared Ignoring air
resistance,
a) find out its height (h) by adding up these three things and Form a quadratic Polynomial in it.​

Answer 1

Step-by-step explanation:

i have the answer for no A

see here v=0

u=14m/s

and

a=5m/s²

now 2as= v²-u²

s=19.6m

and b answer is the above equation
