Answer:
h = 14.4 m
Explanation:
The height can be calculated by energy conservation:
<u>Where</u>:
W: is the work
: is the potential energy
: is the rotational kinetic energy
: is the transitional kinetic energy
Initially, the wheel has rotational kinetic energy and translational kinetic energy, and then when stops it has potential energy.
<u>Where</u>:
I: is the moment of inertia = 0.800 mr²
ω₀: is the angular speed = 25.0 rad/s
m: is the mass = P/g = 397 N/9.81 m*s⁻² = 40.5 kg
v: is the tangential speed = ω₀r²
Now, by solving the above equation for h we have:
Therefore, the height is 14.4 m.
I hope it helps you!
