We have that the maximum rank of the kangaroo is given by:
R = v0 ^ 2 sin (2θ) / g
where,
v0 = initial velocity
θ = angle of the velocity vector formed from the horizontal
g = gravity
Clearing the speed we have:
v0 ^ 2 = (R * g) / (sin (2θ))
Substituting values
v0 = root (((11) * (9.8)) / (sin (2 (21 * (pi / 180)))))
v0 = 12.69 m / s
answer
its takeoff speed is 12.69 m / s
Answers:
1) flow of traffic = 
2) average speed = 
3)density of traffic = 
Explanation:
1) to find flow of traffic
we use the relation

where q is the traffic flow and h is average time headway.

insert the value

2) to find average traffic speed
use the relation

where u is average speed S is average spacing and h average time

so inserting the values

3) density of traffic

where K is density of traffic q is flow of traffic and u is average speed
inserting values from above solved parts
