14) (Conservation of linear momentum) An air cart of mass m=1 kg and speed vo-Im's moves toward second identical air cart that is at rest. When the carts collide, they stick together and move as one a) Using the conservation of linear momentum, calculate the velocity ve when the carts stick together (this is also the velocity of the center of mass after collision). b) Calculate the kinetic energy before and after collision. Is the collision elastic Without any calculation,...

1. A 30 cm spring with constant 70 N/m is compressed to 10 cm and placed between two carts. Cart A has mass m Skg and mg is unknown. Initially the system is at rest. After it is released it is observed that cart A has three times the velocity of cart B. a) What force must be exerted initially to keep the spring compressed? b) What is the work done to compress the spring? c) By considering conservation of...

OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...

Angular Momentum and Inelastic Collisions Two balls, each with mass M/2, are attached to the ends of a thin rod of length L = 0.45 m and negligible mass. The rod is free to rotate in a horizontal plane without friction about a fixed vertical axis through its center. With the rod initially at rest (as shown), two wads of wet putty hit the balls at the same time and stick to them. Assume that the wads of putty have...

Linear Momentum of an object is conserved At all times b. Only when the net external force on the object is Zero When the net external torque on the object is Zero d. Never A truck of mass 4000 (kg) is moving at 10 (m/s). A car of mass 1000 (kg) is moving at 40 (m/s). So, the truck’s momentum, compared to the car, is Greater b. Smaller c. the same d. Cannot say without knowing their accelerations A 1000...

+ Conservation of Momentum Ph X Phy 1010-F19-Chapter 6-PH X webassignunet/web/Student/Assignment-Responses/submthdep 219474888tagssautosave C dimension. The system consists of the two objects and the only forces affecting the motion are the internal forces betwoen them during collision. ANALYZE (A) Determine the velocity after collision Because no external force acts, the colligion does not change the total momentum of the system of two particles. We set the total momentum before collision to the total momentum afterward: myVsm (m + m)v The final...

Two cars collide (No external forces) Car 1 has a mass of 2000kg and a velocity of 40 m/s westward. After colliding with the second car (velocity unknown) the 1st car has a velocity of 10 m/s westward. 1st car momentum = 80000 Ns west 1st car velocity change = 30 m/s east. 1st car change in momentum = 60,000 Ns east. If a 1st passenger (m=50kg) is riding the first car, what impulse does the first car apply on...
