Q. A stone is dropped down a well and a splash is heard 2.4s later. Determine the distance from the top of the well to the surface of the water.
Q. A cord is wrapped around the rim of a solid uniform wheel 0.300 in radius and of mass 7.80 . A steady horizontal pull of 40.0 to the right is exerted on the cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearings on a horizontal axle through its center. what is the angular acceleration of the wheel?
Hair dryer draws a current of 9.2a. How long does it take 1.9*10^3 C of charge pass through? How many electrons does this represent.
A 3500 kg block falls vertically through 5 m and then collides with a 400 kg pile, driving it 3.0 cm into bedrock. Assuming that the block-pile collision is completely inelastic, find out the magnitude of the average force on the pile from the bed..
A wooden raft has a mass of 76 kg. When empty it floats in water (density 1000 kg/m3) with 51 percent of its volume submerged. What mass of sand can be put on the raft without it sinking.
In a popular amusement park ride, a rotating cylinder of radius 4.00 m is set in rotation at an angular velocity of 6.00 rad/s. The floor then drops away, leaving the riders suspended against the wall in a vertical position.
A bag of cement of weight 375 N hangs from three wires as suggested in Figure P5.18. Two of the wires make angles θ1 = 55.0° and θ2 = 25.0° with the horizontal. If the system is in equilibrium, find out the tensions in the wires.
A gymnast of mass 55.0 hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value for the acceleration of gravity.
