Two blocks slide toward each other along a horizontal surface ............
Two blocks slide toward each other along a horizontal surface of negligible friction and collide head-on. The masses and the velocities of the blocks prior to the collision are shown above. During the collision, the impulse on the block of mass 6M has magnitude J. The impulse on the block of mass 4M during the collision has magnitude2J/3 3J/4 4J/3 31/2
Two blocks of mass 0.30g and 0.20g are moving towards each other along a horizontal frictionless surface with velocities of 0.500m/s and 1.000m/s respectively. c. Find the final velocity of each block if the collision is completely elastic.
Two homogeneous identical square blocks are stacked atop each other on a horizontal surface. Friction between the top block (block A) and the bottom block (block B) is described by and but there is no friction between the bottom block (block B) and the horizontal surface. Starting at rest, the top block is pulled to the right with a force which is applied at the midheight. Let , 4 inches, and . Assume neither blocks tips, and remember that Below the figure to the...
Two fun-loving otters are sliding toward each other on a muddy (and hence frictionless) horizontal surface. One of them, of mass 8.00 kg , is sliding to the left at 5.00 m/s , while the other, of mass 5.65 kg , is slipping to the right at 5.00 m/s . They hold fast to each other after they collide. Find the magnitude of the velocity of these free-spirited otters right after they collide.. How much mechanical energy dissipates during this...
3. (III) Three blocks on a frictionless horizontal surface are in contact with each other as shown in Fig. 4-54. A force F is applied to block A (mass mA). (a) Draw a free-body dia- gram for each block. Determine (b) the acceleration of the system (in terms of mA, mB, and mc), (c) the net force on each block, and (d) the force of contact that each block exerts on its neighbor. (e) If mA mB mc- F 96.0N,...
Two blocks are in contact with each other on a frictionless surface. The left block (block 1) weighs 2kg and the right block (block 2) weighs 3kg. A rightward force of 20N is applied to the left block and a leftward force of 10N is applied to the right block. Determine the force that each block exerts on the other.
Problem 3 (20 points: Two blocks, mA 12.0 kg, mB-5.0 kg slide along a frictionless horizontal surface towards one another as shown below. Assuming the collision is perfectly elastic, determine the velocity of each block after impact, the total amount of kinetic energy the system loses, and the magnitude of the impulse felt by block A during the collision.

3. Two gliders are moving toward each other on a horizontal track. Glider A has a mass of 500 g and is moving with a velocity of 50 cm/s. Glider B has a mass of 200 g and is moving with a velocity of -50 cm/s. After a head-on collision, glider A moves with a velocity of 20 cm/s and glider B moves with a velocity of 25 cm/s. a. Calculate the total initial and final momenta of the two...
1. Two blocks are travelling toward each other. The first has a speed of V, cm/seo and the second speed of V, cm/sec. After the collision the second is observed to be travelling with a speed of U cm/sec in a direction opposite to its initial velocity. If the weight of the first block is trice that of the second, determine: a. the velocity of the first block after collision; b. whether the collision was elastic or inelastic.
Two blocks are pushed along a frictionless surface. The static coefficient of friction between the blocks is .70 mm is the maximum force F that can be applied to the lower block (as shown on the diagram) Such that the upper block does not slide
