A horizontal force of 40 N acting on a block on a frictionless level surface produces an acceleration of 2.5 m/s2. A second block, with a mass of 4.0 kg, is dropped onto the first. What is the magnitude of the acceleration of the combination of blocks if the same force continues to act? (Assume that the second block does not slide on the first block.)
Problem #4 A 10 kg box resting on a horizontal, frictionless surface is attached to a 4 kg block by a thin light rope that passes over a frictionless pulley. The pulley has a shape of a uniform solid disk of mass 4.5 kg and a radius of 0.55 m. After the system is released 10 kg box moves to the right, 4 kg block moves down and the pulley rotates clockwise. Find: (a) the magnitude of the tension (in...
An object with mass m1 = 4.70 kg, rests on a frictionless horizontal table and is connected to a cable that passes over a pulley and is then fastened to a hanging object with mass m2 = 11.7 kg, shown in the figure. as (a) Find the magnitude of the acceleration of each object m/s2 a1= m/s2 a2 (b) Find the tension in the cable N
Question 6 1 pts A box of bananas weighing 40.ON rests on a horizontal surface. The coefficient of static friction (us) between the box and the surface is 0.40 while the coefficient of kinetic friction (uk) is 0.20. If a monkey applies a constant horizontal force of 6.0 N, and the box is initially at rest, what is the magnitude of the friction force 1 minutes after the monkey starts pushing? 16.0N 8.0 N Unable to determine O 0.ON 18.0N...

A textbook of mass 1.92 kg rests on a frictionless, horizontal surface. A cord attached to the book passes over a pulley whose diameter is 0.150 m , to a hanging book with mass 2.94 kg . The system is released from rest, and the books are observed to move a distance 1.29 m over a time interval of 0.780 s Part A What is the tension in the part of the cord attached to the textbook? Part B What...
QUESTION 1 Part A A box of mass m1 rests on a smooth, horizontal floor next to a box of mass m2. Suppose the force of 20.0 N pushes on two boxes of unknown mass. We know, however, that the acceleration of the boxes is 1.20 m/s2 and the contact force has a magnitude of 4.45 N. Find the mass of box 1 and box 2. Express your answers using three significant figures separated by a comma. QUESTION 2 A...
