Agirl, standing on the roof of a house which is 5.00 m high, throws a stone vertic upward. it strikes the ground 7.00 s after being thrown. calculate: the initial velocity of the stone the maximum height the stone reaches above a. b. i. the roof ii. the ground and c.

Explanation:

Given

Height of roof=5 m

Time taken by stone to reach ground 7 s

Let u be the initial velocity

therefore maximum height is h

time taken to reach max height

v=u+at

0=u-gt

Now time taken to reach ground is

total time is

Squaring both side

u=33.58 m/s

therefore

h=57.55 m

maximum height from ground is 57.55+5=62.55 m

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
