The velocity-time graph of a stone thrown
vertically upward with an initial velocity
30ms-1 is shown in the figure. The velocity
in the upward direction is taken as positive
and that in the downward direction as
negative. What is the maximum height to
which the stone rises?

Answer: it is 45m
Explanation:
V2=U2+2as
V=0
U=30ms-1
a=-g
Therefore....
U2=2gs
30×30/2×10=s
S is 45

Answer:
45.87
Explanation:
Lets see the data we have
initial velocity = 30ms-1
acceleration = -9.81 ms-1
we need to calculate maximum height and at maximum height velocity will be zero
so the best formula to use will be
= 2as
v = 0
so s =
s =
s = 45.87
