ebAssign 110 N 40 ASK YOUR TEACHER 3. DETAILS SERCP11 4.7.P.065.MI. Objects with masses m, = 15.0 kg and m, = 8.0 kg are connected by a light string that passes over a frictionless pulley as in the figure below. If, when the system starts from rest, m, falls 1.00 m in 1.78 s, determine the coefficient of kinetic friction between m, and the table. 4. DETAILS SERCP11 5.2.OP.015. ASK YOUR TEACHER A 7.80 g bullet is initially moving at 620 m/s just before it penetrates a block of wood to a depth of 5.80 cm. (a) What is the magnitude of the average frictional force (in N) that is exerted on the bullet while it is moving through the block of wood? Use work and energy considerations to obtain your answer. (b) Assuming the frictional force is constant, how much time (in s) elapses between the moment the bullet enters the block of wood and the moment it stops moving?
