We cannot conclude that either β0 or β1 are equal to zero, where β0 is the estimated price for a bicycle weighing zero pounds and β1 is the estimated change in price for a one pound weight increase. Both interpretations are reasonable.

1D. A 1000N block A is suspended from a rope that runs around the fixed pegs B and C. The coefficient of friction between the pegs and the rope is µs = 0.25. Determine the total angle of wrap for both pegs and the minimum force P needed to hold the block in static equalibrium. $\beta_{Tot}$ = $P_{Min}$ = P C 40° B A 1000N (3 pts) (2 pts)

Energy conservation with nonconservative forces: Block 1 and block 2 have the same mass, m, and are released from the top of two inclined planes of the same height making 30° and 60° angles with the horizontal direction, respectively. If the coefficient of friction is the same in both cases, which of the blocks is going faster when it reaches the bottom of its respective incline? We must know the actual masses of the blocks to answer. Block 2 is faster. There is not enough information to answer the question because we do not know the value of the coefficient of kinetic friction. Both blocks have the same speed at the bottom. Block 1 is faster.
