Do I use the concept of elastic collision and its related linear momentum and velocity equations? That is how I've solved it and got 535 m/s. Ths velocity decreases because the potential energy is supplied to moving the cannon?
The conservation of momentum tellsus that the momentum of a system ofinteracting particles must remain constant ifthere are no outside forces. However, whentwo cars collide head-on, they can almostinstantly come to rest (and crumpleunfortunately). This system is essentiallyisolated since the only important interactionsare between the two cars. How can youreconcile these two observations?
Hi! I'm hoping for complete solutions since I’m having a hard time with this. Kindly skip if unsure or not willing to answer the subitems (because these are all connected for one item). Thanks in advanced! :) A puck with mass mA = 3.14 [g] moves eastward with speed vA = 6.25 [m/s]. It then collides with another puck of mass mB = 2.99 [g] and is moving northward with a speed vB = 3.65 [m/s]. After the collision, puck A now moves at 34.0° north of east, while puck B moves at 35.0° south of east. A. What are the speeds of the two pucks after the collision? Speed of puck A after the collision: _______ [m/s] Speed of puck B after the collision: _______ [m/s] B. Is energy lost or gained in the system? Support your answer by calculating the change in mechanical energy of the system. The change in mechanical energy is _______ [J]. Thus energy is _________________ (CHOICES: gained in the system, lost in the system, did not change).
