Consider a block of mass \(m\) attached to two springs, one on the left with spring constant \(k_1\) and one on the right with spring constant \(k_2\). Each spring is attached on the other side to a wall, and the block slides without friction on a horizontal surface. When the block is sitting at \(x\) = 0, both springs are relaxed.
A 16-kg block is attached to a cord that is wrapped around the rim of the flywheel and hangs vertically down. When the block is released and the cord unwinds, the acceleration of the block is (make a sketch): a. 0.15g. b. 0.56g. c. 0.84g. d. g. e. 1.3g . 5. A cylinder of radius R = 6.0 cm is resting on a rough horizontal surface.
Jun 09, 2019 · 36.A car P is moving with auniform speed of 5(3 1/2) m/s towards a carriage of mass 9 Kg at rest kept on the rails at a point B as shown in fig. The height AC is 120 m. The height AC is 120 m. Cannon balls of 1 Kg are fired from the car with an initial velocity 100 m/s at an angle 30° with the horizontal.
1.7 A force of magnitude 7.50 N pushes three boxes with masses m1 =1.30 kg, m2 =3.20 kg, and m3 =4.90 kg, as shown in Figure 1.7 . Find the magnitude of the contact force (a) between boxes 1 and 2, and (b) between boxes 2 and 3. (6.64N, 3.91N) Figure 1.7 1.8 Two boxes sit side-by-side on a smooth horizontal surface. The lighter box has a mass ...
Its specific use is in testing the trueness of a finished surface, testing a try square, providing adequate bearing surface for V-block and angle plates, etc., in scribing work. It is a cast iron plate having a square or rectangular top perfectly planed true and square with adjacent machined faces.
(1) zero (2) smaller, but greater than zero (3) larger (4) the same 11 The work done in moving a block across a rough surface and the heat energy gained by the block can both be measured in (1) watts (3) newtons (2) degrees (4) joules Note that question 12 has only three choices. 12 Two weightlifters, one 1.5 meters tall and one
Then calculate the max static friction force on the 5 kg block. Since the blocks aren't moving, the opposing forces are equal. The friction force equals the tension force, which also equals the force of gravity for the right block. This means we can set the max static friction equal to the force of gravity for the right block.
