The velocities of commuter trains A and B are as shown. Knowing that the speed of each train is constant and that B reaches the crossing 10 min after A passed through the same crossing, determine the relative velocity of B with respect to A and the distance between the fronts of the engines 3 min after A passed through the crossing. Given, VA =70 km/h and up=52 km/h. (Round the final answers to two decimal places.) alvenoches rent in...

3.) Given: The link shown is guided by two blocks at A and B, which move in the fixed slots. If the velocity of block A is 2 m/s downward, determine the velocity of block B at the instant 0 = 450 Note: The Velocity-Difference Equation is as follows: Yg - VA + VBIA - VA+WAB ®RBIA In addition, the following value for angular velocity is given: Ô = 7rad/s (fixed frame link 1) Find: (a) State the velocity of...
Two blocks move along a linear path on a nearly frictionless air track. One block, of mass 0.105 kg, initially moves to the right at a speed of 4.50 m/s, while the second block, of mass 0.210 kg, is initially to the left of the first block and moving to the right at 7.10 m/s. Find the final velocities of the blocks, assuming the collision is elastic. velocity of the 0.105 kg block = velocity of the 0.210 kg block...
Two blocks move along a linear path on a nearly frictionless air track. One block, of mass 0.116 kg, initially moves to the right at a speed of 5.20 m/s, while the second block, of mass 0.232 kg, is initially to the left of the first block and moving to the right at 7.30 m/s. Find the final velocities of the blocks, assuming the collision is elastic. Velocity of the .116 kg block to the right: Velocity fo the .232...
Three Velcro blocks, i.e Velcro on their ends, are shown below. The masses and velocities of the blocks are m1 = 7.6 kg, v, = 11.0 m/s. m2 = 10.0 kg, v2 = 4.0 m/s and m3 = 4.0 kg, v3 = 2.0 m/s. Mass m, collides with m2 and the two collide with m3, both collisions perfectly inelastic. The masses then collide with a spring (not shown) with a spring constant of 2.7 times 104 N/m. (a) What is...
A 2.5-lb block is supported as shown by a spring of constant k = 2 lb/in. that can act in tension or compression. The block is in its equilibrium position when it is struck from below by a hammer that imparts to the block an upward velocity of 90 in./s. Determine the position, velocity, and acceleration of the block 0.85 s after it has been struck by the hammer. (Round the final answers to two decimal places. A 177
