T (N)
The log has a mass of 500 kg and rests on the ground for
which the coefficients of static and kinetic friction are
Hy = 0.5 and ug = 0.4, respectively. The winch delivers a
horizontal towing force T to its cable at A which varies as
shown in the graph. Determine the speed of the log when
t = 5 s. Originally the tension in the cable is zero. Hint: First
determine the force needed to begin moving the log.

Read Masterarrow_forwardWe often think of friction and air resistance as forces that we want to minimize because they can hinder the motion of an object. But they are not always undesirable, and in fact, can be an essential element in a machine or process. Identify one or two applications that depend on friction and air resistance. Explain how friction or air resistance works in those situations and what would happen if there were no friction or air resistance.

- >V=0 d (m A block of mass m is on an inclined ramp. The ramp makes an angle with respect to the horizontal, as shown. The ramp has friction, with coefficient of kinetic friction and static friction μs. This experiment takes place on earth. The block has an initial speed of v up the ramp. It travels a distance d along the ramp before it stops. There are no numbers in this problem! Answer all questions in terms of the given variables (g, m, µk, µs, 8, v, d) only. Do not use any other variables. a) Draw a free body diagram clearly showing all the forces acting on the block while it is moving up the ramp. b) Calculate the work done by the Normal force as the block travels the distance d. Is it positive, negative, or zero? c) Calculate the work done by the Weight force as the block travels the distance d. Is it positive, negative, or zero? d) Calculate the work done by the Friction force as the block travels the distance d. Is it positive, negative, or zero? e) If the block comes to rest,…arrow_forwardved 161 A single cable is wrapped from the center of pulley A, around pulley B, and around pulley A.
