Boxcar #1 has a mass of 2000 kg. Boxcar #2 has a mass of 1200 kg. Boxcar #1 is moving at 12.00 m/s to the right before they hit and stick together.

A) Suppose that the velocity of Boxcar #2 before the collision is 8.00 m/s to the right. What is the velocityafter the totally inelastic collision?

B) Suppose, instead, that the speedafter the totally inelastic collision is 3.00 m/s. What was the velocity of Boxcar #2 before the collision? Give all possible answers.

two subway cars as shown in Figure 1 have mass m = 2000 kg and are connected by a coupler that can be modeled as a spring of stiffness k = 280,000 N/m. Use Newton’s method to derive the equations of motion, calculate the natural frequencies and determine the associated mode shapes. also, find the time response x1(t) and x2(t) of the subway initial conditions: x(0)= [ 0, 0.2] with zero initial velocity vector.

Two cars collide at an intersection. Car A, with a mass of 2000 kg , is going from west to east, while car B, of mass 1400 kg , is going from north to south at 14.0 m/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of...

A block of mass 2 kg and a block of mass 3 kg are sliding on a frictionless surface. They collide and stick together.

A spring with a mass of 2 kg has a damping constant 14 kg/s. A force of 3.6 N is required to keep the spring stretched 0.3 m beyond its natural length. The spring is stretched 0.7 m beyond its natural length and then released. Find the position of the mass at any time t. (Assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.) What is x(t)?
