A block of mass 1.7 kg is attached to a horizontal spring that has a force constant 800 N/m as shown in the figure below. The spring is compressed 2.0 cm and is then released from rest. a b TE www |—*— x- x = 0 (a) A constant friction force of 3.9 N retards the block's motion from the moment it is released. Using an energy approach, find the position x of the block at which its speed is a maximum. cm (b) Explore the effect of an increased friction force of 13.5 N. At what position of the block does its maximum speed occur in this situation? cm
