1) Block B falls a distance of .6m. Find velocity of block A
2) Before it pauses for a moment what is Max Distance of B


Blocks A and B, with masses Ma= 5kg and Mb= 3kg, respectively, are connected by a spring of stiffness k= 20 N/m and unstretched length of 0.75m. The blocks are at rest and seperated by the distance 0.75m when block B is given a velocity to the rightwith magnitude v0=15m/s. The friction between blocks and the horizontal surface on which they rest is negligible. The picture given looks like: [A]---------[B] where the dashed line is the spring. Determing the maxium...
Block A of mass, mA = 1.7 kg is shot from a spring device of spring constant, k = 700 N/m along a frictionless horizontal surface. The initial compression of the spring is 0.300 m. The shot makes the block rise to another horizontal level at a height h= 1m above the first. On this horizontal it collides with another stationary block B of mass mB = 3.5 kg. The blocks stick together and encounter a rough surface. The blocks...
3. A block with a mass of 5kg is given a kick up a ramp angled at 35º such that its initial speed is 7.8 m/s. The block travels up the ramp for 4.3m before it stops moving and starts to slide back down. a) Find the initial mechanical energy (K + U) of the block. b) Find the final mechanical energy of the block. c) The answer to (a) is bigger than the answer to (b). That means the...
Part A Block A has a mass mA and is attached to a spring having a stiffness k and unstretched length lo- Another block B, having a mass mB, is pressed against A so that the spring deforms a distance d. The coefficient of kinetic friction between the blocks and the ground is μk. (Figure 1) Assuming separation does occur what is the distance the blocks slide on the surface before they separate? Express your answer in terms of some...
Block A of mass mA is moving horizontally with speed Va along a frictionless surface. It collides elastically with block B of mass mB that is initially at rest. After the collision block B enters a rough surface at x =0 with a coefficient of kinetic friction that increases linearly with distance μ(x) = bx for 0 ≤ x ≤ d, where b is a positive constant. At x=d block B collides with an unstretched spring with spring constant k...
1. (30 points) A 2-kg block A is pushed up against a spring compressing it a distance r-0.1 m (i.e., the spring is unattached to the block). The block is then released from rest and slides down the 20° incline u it strikes a 1-kg sphere B that is suspended from a 1-m inextensible rope. The spring constant 800 N/m, the coefficient of friction between A and the ground i length of the spring d-1.5, and the coefficient of restitution...

A bullet (0.1 kg) initially moving at speed u is embedded inside block 1 (4 kg) initially at rest at A which travels 8 m in a rough region (uk = 0.2) to B at speed of 12 m/s, then travels to a frictionless region from B to C, then to a rough region (Uk = 0.2) after point C. Then bulletblock 1 collides with block 2 (15 kg) which is initially at rest and connected with a spring of...
