Question

Kangaroo is capable of jumping to a height of 2.6 to determined you take off speed of the kangaroo acceleration due to gravity is equal to 10 m/s^2​

Answer 1

Answer:

here is your answer mate...

Explanation:

a = -10 m/s2

vf = 0 m/s

d = 2.6 m

Find:

vi = ??

vf2 = vi2 + 2*a*d

(0 m/s)2 = vi2 + 2*(-10 m/s2)*(2.6 m)

0 m2/s2 = vi2 - 52 m2/s2

52 m2/s2 = vi2

vi = 7.188 m/s
