A crate sits on a flat-bed truck that is traveling with a speed of 50 km/h on a straight, level road. If the coefficient of static friction between the crate and the truck bed is 0.30, in how short a distance can the truck stop with a constant acceleration without the crate sliding?
Answer to relevant QuestionsA 5.0-kg block at rest on a frictionless surface is acted on by forces F1 = 5.5 and F2 = 3.5 N as illustrated in Fig. 4.33. What additional force will keep the block at rest? A 5.0-kg wooden block is placed on an adjustable wooden inclined plane. (a) What is the angle of incline above which the block will start to slide down the plane? (b) At what angle of incline will the block then slide down ...For the apparatus shown in Fig. 4.40, what is the minimum value of the coefficient of static friction between the block (m3) and the table that would keep the system at rest if m1 = 0.25 kg, m2 = 0.50 kg, and m3 = 0.75 kg? A 2.50-kg block is placed on a rough surface inclined at 30o. The block is propelled and launched at a speed of down the incline and comes to rest after sliding 1.10 m. (a) Draw the free-body diagram of the block while it ...Identify the direction of the friction force in the following cases: (a) A book sitting on a table; (b) A box sliding on a horizontal surface; (c) A car making a turn on a flat road; (d) The initial motion of a machine ...
