v = 25 m/s
so
25 = omega R = omega * 0.32
omega = 25 / 0.32 radians/second
I = 4 * 0.8 = 3.2 kg m^2
Translational = (1/2) m v^2
Rotational = (1/2) I omega^2
A truck with a total mass of 1.75x103
kg has wheels of radius 32.0 cm and
moment of inertia of 0.800 kg-m2
. Find the truck’s (a) translational energy and (b)
rotational energy when the truck is moving at a speed of 25.0 m/s
