4. We use the results from section 11.3. (a) We substitute IM R = 2 5 2 (Table 10-2(f)) and a = – 0.10 g into Eq. 11-10: −= + =− 010 1 75 2 5 22 . sin / g g MR MR g θ ch which yields = sin –1 (0.14) = 8.0°. (b) The acceleration would be more. We can look at this in terms of forces or in terms of energy. In terms of forces, the uphill static friction would then be absent so the downhill acceleration would be due only to the downhill gravitational pull. In terms of energy, the
