Answer:To calculate the momentum of an object, we use the formula:Momentum = mass x velocityGiven that the motorcycle has a mass of 250 kg and is traveling at a velocity of 26 m/s, we can calculate its momentum as follows:Momentum = 250 kg x 26 m/sMomentum = 6500 kg·m/sTherefore, the momentum of the 250 kg motorcycle traveling at 26 m/s is 6500 kg·m/s.
