A student has six textbooks, each with a thickness of 4.0 cm and a weight of 30 N. What is the minimum work the student would have to do to place all the books in a single vertical stack, starting with all the books on the surface of the table?
Answer to relevant QuestionsA 1.50-kg mass is placed on the end of a spring that has a spring constant of 175 N/m. The mass– spring sys-tem rests on a frictionless incline that is at an angle of from the horizontal (Fig. 5.31). The system is eased ...A 1.00-kg block (M) is on a flat frictionless surface (Fig. 5.32). This block is attached to a spring initially at its relaxed length (spring constant is 50.0 N/m). Alight string is attached to the block and runs over a ...Suppose the simple pendulum in Exercise 54 were released from an angle of 60o. In Exercise A simple pendulum has a length of 0.75 m and a bob with a mass of 0.15 kg. The bob is released from an angle of relative to a ...A 1.00-kg block (M) is on a frictionless, 20o inclined plane. The block is attached to a spring (k = 25 N/m) that is fixed to a wall at the bottom of the incline. Alight string attached to the block runs over a frictionless ...How much power must you exert to horizontally drag a 25.0-kg table 10.0 m across a brick floor in 30.0 s at constant velocity, assuming the coefficient of kinetic friction between the table and floor is 0.550?
