Question #6184

A kangaroo is capable of jumping to a height of 2.62 m. determine the takeoff speed of the kangaroo.

Expert's answer

Due to energy conservation law

Mgh=Mv^{2}/2

where M-mass of kangaroo, v- take off speedHence v=sqrt(2gh)=sqrt(2*10*2.62)=7.2 m/s

Mgh=Mv

where M-mass of kangaroo, v- take off speedHence v=sqrt(2gh)=sqrt(2*10*2.62)=7.2 m/s
