In the figure, block A (mass 1.6 kg) slides into block B (mass 2.4 kg), along a frictionless surface. The directions of velocities before and after the collision are indicated; the corresponding speeds are vAi = 5.4 m/s, vBi = 2.0 m/s, and vBf = 4.5 m/s. What is velocity vAf (including sign, where positive denotes motion to the right)? Number Units the tolerance is +/−1 in the 2 nd significant digit

In the figure, block 2 of mass 2.20 kg oscillates on the end of a spring in SHM with a period of 18.00 ms. The position of the block is given by x = (1.10 cm)cos⁡(ωt + π/2). Block 1 of mass 4.40 kg slides toward block 2 with a velocity of magnitude 6.30 m/s, directed along the spring's length. The two blocks undergo a completely inelastic collision at time t = 4.50 ms. (The duration of the collision is much less than the period of motion. ) What is the amplitude of the SHM after the collision? Number Units

A 4.41-g bullet is moving horizontally with a velocity of +354 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1199 g, and its velocity is +0.644 m/s after the bullet passes through it. The mass of the second block is 1576 g . (a) What is the velocity of the second block after the bullet imbeds itself? (b) Find the ratio of the total kinetic energy after the collision to that before the collision. (a) Before collision (b) After collision (a) vblock2 = Number Units (b) KEafter/KEbefore = Number Units

In the figure, a 4.5 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is v0 = 5.4 m/s, the height difference is h = 1.1 m, and μk = 0.602. Find d. Number Units
