PLEASE HELP DUE TONIGHT

Answer 1

The height & speed are mathematically given as

t = 0.2 s

u = 4 m/s

What is the height & speed?

Generally, the equation for height is  mathematically given as

h = 0.2gt^2

Therefore

0.2 = 0.5 * 9.8 *$t^2$

0.2 = 4.9 *$t^2$

t = 0.2 s

b)

In conclusion, the initial speed is

s = ut

Therefore

u = 0.8 / 0.2

u = 4 m/s
