A block of weight 45.3 N is hanging from a rope. The tension from the rope is pulling upward on the block. The block is accelerating downward at a rate of 1.46 m/s2. What is the magnitude of the tension in the rope?
A 32.9-kg child swings on a rope with a length of 6.11 m that is hanging from a tree. At the bottom of the swing, the child is moving at a speed of 4.2 m/s. What is the tension in the rope?
Please help! 10, A block of mass m = 3.50 kg is hanging from a massless cord that is wrapped around a pulley (mass = 5.00 kg) as shown in the figure. The cord does not slip relative to the pulley as the block falls. Find the magnitude of the tension in the cord. (moment of inertia of the pulley áMr2)
20) The density of a block of iron is 7,860 kg/m². The density of mercury is 13,950 kg/m² This block of iron will: a) float in mercury b) sink in mercury c) hang motionless in mercury d) none of the above
A light rope is attached to a block with mass 3.00 kg that rests on a frictionless, horizontal surface. The horizontal rope passes over a frictionless, massless pulley, and a block with mass m is suspended from the other end. When the blocks are released, the tension in the rope is 15.3 N . part a) Draw free-body diagram for the 3.00-kg block. Assume block is moving to the right. Draw the vectors starting at a black dot. The location...
A 56-kg student runs at 6.4 m/s , grabs a hanging 10.0-m-long rope, and swings out over a lake. He releases the rope when his velocity is zero. What is the angle θ when he releases the rope? What is the tension in the rope just before he releases it? What is the maximum tension in the rope during the swing?
A hanging iron wire with diameter 0.5 mm (0.5 × 10-3 m) is initially 1.10 m long. When a 108 kg mass is hung from it, the wire stretches an amount 29.6 mm. A mole of iron has a mass of 56 grams, and its density is 7.87 g/cm3. Find the approximate value of the effective spring stiffness of the interatomic force.
A hanging iron wire with diameter 1.5 mm (1.5 × 10-3 m) is initially 1.50 m long. When a 104 kg mass is hung from it, the wire stretches an amount 4.33 mm.
