Question

consider the "can race" at the front of the class room. the radius of hunt's tomato sauce is R=3 cm, it has a mass of 227 g, and it has a moment of inertia of I = 1.24 x 10^ -4 kgm^2 .

A) draw a free-body diagram of the hunts tomato sauce can, while it's rolling down the ramp.

B) at some point in the race, one of the cans is rotating at w= 2 rad/s. find the angular speed in degree/hour.

C) determain the LINER speed of the tomato sauce can when it reaches the bottom of the ramp (the top of the ramp is 0.8 m hight)

Explanation / Answer

Angular Momentum L = I1 W1

L = 1.24 *10^-4 * 2

L = 2.48 *10^-4 Kgm^2/s

------------------------

angular velocity W = V/r

linear Velocity V = W r

V = 2 * 0.03

V = 0.06 m/s
