A solid block of mass m2 = 2.3 kg, at rest on a horizontal frictionless surface, is connected to a relaxed spring (with spring constant k = 260 N/m whose other end is fixed. Another solid block of mass m1 = 2.2 kg and speed v1 = 3.3 m/s collides with the 2.30 kg block. If the blocks stick together, what is their speed immediately after the collision?What is the maximum compression of the spring?

In the figure, block 1 of mass 2.00 kg slides from rest along a frictionless ramp from height h = 2.60 m and then collides with stationary block 2, which has mass 4.50 kg. The spring shown has a spring constant of 31.5 N/m. (a) How fast is block 1 moving just before contacting block 2? (b) Assume the whole path is frictionless, and the collision is completely inelastic, how far does the spring compress? (c) Now, assume you test...

A 1.0-kg block (Block 1) at rest on a horizontal frictionless surface is connected to unstretched spring Ck 400 N/m) whose other end is fixed. A 2.0-kg block (Block 2) moving at 4.0 m/s collides with Block 1. Block 2 is found to move leftward with a speed of 1 m/s after collision. (1) What is the speed of Block 1 after collision? (6 pts) (2) What maximum compression of the spring occurs when Block I momentarily stops? (6 pts)...

A 68-kg man stands on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.2 m/s in 0.77 s. The elevator travels with this constant speed for 5.0 s, undergoes a uniform negative acceleration for 1.8 s, and then comes to rest. (a) What does the spring scale register before the elevator starts to move? N (b) What does the spring scale register during the first 0.77 s of the elevator's ascent?...

Consider a 77.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.08 m/s in 0.900 s. It travels with this constant speed for the next 5.00 s. The elevator then undergoes a uniform acceleration in the negative y direction for 1.70 s and comes to rest. (a) What does the spring scale register before the elevator starts to move? N (b) What does the spring scale register during...

a block with a mass of 2.5 kg starts from rest at the top of the
apparatus shown below. it then slides without friction down the
incline, and collides with a spring attached to a wall. The spring
has a spring constant of K=120N/m. Using the principle of energy
conservation,
a. find the initial gravitational potential energy of the block
at point A
b. find the kinetic energy of the block at point B
c. what is the velocity of...

2. Refer to the diagram shown here (a side view, not to scale). Two blocks with masses m, and m, respectively, are connected via a massless thread over a pulley wheel. The wheel is a solid, uniform disk with mass m, outer radius R, and a frictionless axle. Initially you hold m, (and therefore the entire system) at rest in the position shown; m, is at rest on level ground. Then you release m,. The data: m,-7.16 kg m, 3.45...
