Kolten Coleman · Answer 1

(a) 5 m/sec

Explanation:

we have given r=1 meter

angular velocity ω = 5 revolution/sec

we have to find the velocity of turbine blade tip

the velocity of turbine blade tip is given by v = rω

where v = velocity of turbine blade tip

r = radius

ω = angular velocity

so v = 5*1 = 5 meter/sec

so the option (a) will be the correct option as in option (a) velocity is given as 5 meter/sec
