Answer:

1) velocity and acceleration will be zero at max height

2)don't know sorry

3)what goes up , comes down

Answer 2

Answer:

(a) velocity and acceleration will be zero at the Max height.

(b) Maximum height =

$\frac{ {u}^{2} }{2g}$

Given : - u = 19.6 m/s

g = 9.8 m/s²

Hence :-

$h = \frac{ {u}^{2} }{2g}$

$\frac{19.6 \times 19.6}{2 \times 9.8}$

$h \: = 19.6$

(c) The values in life that we learn from this concept is that what goes up comes down.
