Calculate the average pressure exerted on the palm of a shot putter’s hand by the shot, if the area of contact is 50 cm^2 and he exerts a force of 780 N on it.
3. A horizontal spring of spring constant 100 N/m is attached to a wall, and a block (A) of mass 5 kg. The block rests on a frictionless table. It oscillates with an amplitude of 10 cm. On top of the block rests a second block (B), held in place only by friction. (A) If block B slips, where is it most likely to do so: near the center of the spring's travel, or near the extremes? Why? (B) How...
Question 1 A 10 kg block rests on a flat frictionless table. A force of 200 N, F2 = 100 N are applied to the box. Also, F3 = 501 on a flat frictionless table. A force of F applied to the box. Also, F = 50 N is applied at an angle of 0 = 30°. These forces cause the block to slide a distance x = 5 m. Calculate (a) the total work done by the forces. (b)...
A block whose weight is 42.6 N rests on a horizontal table. A horizontal force of 34.1 N is applied to the block. The coefficients of static and kinetic friction are 0.640 and 0.390, respectively. Will the block move under the influence of the force, and, if so, what will be the block's acceleration? If the block does not move, give 0 m/s2 as the acceleration.
Help, please The envelope of an elastic balloon exerts a pressure on its contents proportional to its area. The balloon is inflated from a volume of 10 L and a pressure of 200 kPa to a volume of 25 L. (a) Calculate the final pressure in the balloon. (b) Calculate the work of the balloon envelope.
A block of mass 300 g rests on a smooth horizontal table and can slide freely without any friction. The block is attached to a spring of spring constant 100 N/m, whose other end is fixed to a wall. The block is pushed horizontally till the spring compresses by 12 cm, and then the block is released from rest. (a) Determine the speed of the block as it crosses the equilibrium point of the spring (i.e, where the spring is...
Block A has a mass of 20 kg and rests on a frictionless table. A cord attached to block A extends horizontally to a pulley at the edge of the table, block B has a 10 kg mass and hangs over the edge attached to the string. How would I calculate the tension in the cord?
A block with mass M = 6.0 kg rests on a frictionless table and is attached by a horizontal spring (k = 130 N/m) to a all. A second block, of mass m = 1.25 kg, rests on top of M. The coefficient of static friction between the two blocks is 0.30. What is the maximum possible amplitude of oscillation such that m will not slip off M?
A block, of weight 100 N, rests on a horizontal surface. The coefficient of kinetic friction between the surface and the block is 0.5. A force, with horizontal component of 40 N and a vertical component of 60 N is applied to the block (i.e., F= 40i +60j Newtons). Calculate the acceleration of the block.
A student in a lab exerts a 25 N force to pull a block a distance of 48 cm. If a total of 11 J of work is done. What is the angle between the force and the displacement?
