Question

A kangaroo is capable of jumping to a height of 5m. Determine the take off speed of
the kangaroo​

Answer 1

Answer:

Maximum height reached by Kangaroo H=2.62

Final velocity at the maximum height v=0

Acceleration due to gravity g=−9.8 m/s

2

(minus sign for downward direction)

Using v

2

−u

2

=2gH

∴ 0−u

2

=2(−9.8)(2.62)

⟹ u=

2(9.8)(2.62)

=7.17 m/s

Answer 2

Answer:

the takeoff speed of Kangaroo is 7.58 per second
