Q. A uniform meter stick is placed on and parallel to the x axis with the 50 cm mark at the origin. It is pivoted at the 50 cm mark. A 5.3 N force is applied at the 21 cm mark, and a (-7.0) N force is applied at the 1 cm mark. Find the net torque on the rod.
Q. An outfielder throws a 0.150 kg baseball at a speed of 39.6 m/s and an initial angle of 34.0° What is the kinetic energy of the baseball at the highest point of its trajectory?
suppose the apparatus as used in this lab: A cube of mass M = 500 g and side length 30 mm is free to spin on an axis through the center of one face. A massless pulley on this axis has a diameter of 2r = 10 mm. An object with m = 50 g is hung from ..
A father (m = 70 kg) and son (m = 45 kg) are standing facing each other on a frozen pond. The son pushes on the father and finds himself moving backward at 3 m/s after they have separated. How fast will the father be moving.
A bucket is made from thin sheet metal. The bottom and top of the bucket have radii of 21.0 cm and 39.0 cm, respectively. The bucket is 30.0 cm high and filled with water. Where is the center of gravity.
Two automobiles, each of mass 900 kg, are moving at the same speed, 15 m/s, when they have an inelastic collision.(a) In what direction and at what velocity does the wreckage move if one car was driving north and one south? (b) In what direction a..
Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles q1, q2 and q3 respectively and free. The approximation sin q = q holds for all three angles, with q3 > q2 > q1. How do the angular frequencies of th..
A 4.86 g bullet moving with an initial speed of vi = 439 m/s is fired into and passes through a 1.06 kg block. The block, initially at rest on a frictionless horizontal surface, is connected to a spring with the spring constant of 832 N/m.
What is the greatest mass that can be accelerated upwards at 2.9 m/s2 if the stress in the cable is not to exceed the elastic limit of the cable, that is 2.2 108 Pa.
A toy airplane is tied to the ceiling with a string. When the airplane's motor is started, it moves with a constant speed of 1.03m/s in a horizontal circle. If the angle the string makes with the vertical is 27°, and the tension of the string is 1N.
A bucket of water is whirled in a vertical circle of radius 90cm,What is the least speed that will keep the water from falling out.
A long, straight wire carries a 25.0 current. An electron is fired parallel to this wire with a speed of 280 in the same direction as the current, 2.30 from the wire.
If the car starts at height h= 3.00 R and the radius is R_1 = 24.0 m, compute the radial acceleration of the passengers while the car is at point C, which is at the end of a horizontal diameter.
A child throws a snowball with a horizontal velocity of 18m/s directly toward a tree, from a distance of 9m and a height above the ground of 1.5m.
