A m = 4.10 kg block is attached to a vertical rod by means of two strings. When the system rotates about the axis of the rod, the strings are extended as shown in the figure, where L is 1.30 m and h is 1.60 m, and the tension in the upper string is 98 N. How many revolutions per minute does the system make?

A block with mass m = 6.2 kg is attached to two springs with spring constants...

A block with mass m = 6.2 kg is attached to two springs with spring constants kleft = 31 N/m and kright = 49 N/m. The block is pulled a distance x = 0.2 m to the left of its equilibrium position and released from rest. 1) What is the magnitude of the net force on the block (the moment it is released)? N 2) What is the effective spring constant of the two springs? N/m 3) What is the...

A block with mass m = 4.2 kg is attached to two springs with spring constants kleft = 34 N/m and kright = 57 N/m. The block is pulled a distance x = 0.22 m to the left of its equilibrium position and released from rest Where is the block located, relative to equilibrium, at a time 0.8 s after it is released? (if the block is left of equilibrium give the answer as a negative value; if the block...

A mass, m=1.4 kg of negligible size, is attached at the end of a uniform rod of length L= 0.99 mm which has mass M= 1.9 kg . What is the moment of inertia of this arrangement if it is to rotate at an axis located at a distance 0.39*L from the end of the rod opposite to the mass, m? (At approximately the point marked with an 'X'.) Calculate the moment of inertia of the rod-mass system given that...

A block of mass m = 2.5 kg is attached to a spring with spring constant...

A block of mass m = 2.5 kg is attached to a spring with spring constant k = 640 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 27° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.11. In the initial position, where the spring is compressed by a distance of d = 0.19 m, the mass is at...

A 2.4 kg block hangs from the bottom of a 2.0 kg, 1.6 m long rod....

A 2.4 kg block hangs from the bottom of a 2.0 kg, 1.6 m long rod. The block and the rod form a pendulum that swings out on a frictionless pivot at the top end of the rod. A 10 g bullet is fired horizontally into the block, where it sticks, causing the pendulum to swing out to an angle of 45 degrees. You can treat the wood black as a point mass. What is the moment of inertia of...
