Answer:

The mass=0.169

The height=57.8

The power=1.63 watts

Explanation:

The formula for mass is 2KE/v^2

v=34×34 KE=98 therefore 2*98/34^2=0.169

The formula for height is v^2/2g

v=34*34 therefore 34^2/2*10=57.8

The formula for power is work/time

in which the work is the kinetic energy =98

and time 1*60secs =60 therefore 98/60=1.63watts
