Since the cars stick together, they will have the same final velocity. Find the velocity of the car with mass 4 kg with respect to ground. D. First convert 500g to kg = 500/1000 = 0.5kg, momentum = 0.5 x 3.5 = 1.75 kg x m/s along the road. Therefore total momentum of the system before collision is equal to the total momentum of the system after collision. Thus "center of momentum" means "center-of … If they are all traveling at the same speed, the car that weighs the most would have the highest momentum. Momentum is conserved whenever the net external force on a system is … A 0.5 kg football is thrown with a velocity of 12 m/s to the right. probably know from the accompanying theoretical course, the conservation of energy and momentum play an important role in physics and their conservation is a consequence of … + Conservation of momentum is applied to the collision. 3.00\text { m/s}. I’ve provided the answers so you can make sure that your work is leading you in the right direction. After the collision, the ball and the person travel with the same velocity (v) across the ice. Apply conservation of momentum along the x-axis. Within some problem domain, the amount of mass remains constant--mass is neither created nor destroyed.
