HW 5.7. A rod of length 20.0 cm has linear density (mass per unit length) given by 1 = 40.0 + 10.0 x, where x is the distance from one end, measured in meters, and is in grams/meter. (a) What is the mass of the rod? (b) How far from the x = 0 end is its center of mass?
A long thin bar (length L = 18 cm, mass 1.8 kg) of uniform density is placed upon a horizontal, frictionless surface. A small rubber puck (mass 250 g) slides towards the bar with a speed (2 m/s) directed perpendicular to the bar. It collides perfectly elastically with the bar at a distance (d) from the center of mass of the bar in such a way that the puck rebounds with a velocity (1 m/s). a) What is the value...
A rod of length 1.00 m has linear density (mass per unit length) given by λ = (40.0 kg/m) + (80.0 kg/m2)x where x is the distance from one end. (a) What is its mass? (b) How far from the x = 0 end is its center of mass?
A uniform, thin bar has a mass of 2 kg and a length of 0.50m. Initially, the bar is balanced horizontally about a pin through its center of mass and orthogonal to its length. A small mass of 0.75 kg is placed on the left end and the system begins to spin. Find: a) the initial angular acceleration of the system b) the maximum angular velocity of the system c) the torque on the system when it has reached the...
A rod of length 30.0 cm has linear density (mass per length) given by: d = 50.0 20.0 x where x is the distance from one end, measured in meters and A is in kg/meter. (a) What is the mass of the rod? (b) How far from the x-0 end is its center of mass?
In a butcher shop, a horizontal steel bar of mass 3.92 kg and length 1.40m is supported by two vertical wires attached to its ends. The butcher hangs a sausage of mass 2.34kg from a hook that is at a distance of 0.20m from the left end of the bar. What are the denotes the tension in the right wire.
Please explain how to derive this and provide the answer. A bar of length L and uniform density is held horizontally against a wall by a pivot at one end and a rope of tension T which pulls up and to the left making an angle θ with the vertical wall. The rope is attached to the bar at a distance l L from the wall. A mass M is resting at the end of the bar. If the bar...
Calculate the mass of a solid gold rectangular bar that has dimensions of 4.00 cm x 10.5 cm x 27.5 cm.
