Question

you have one heavy cart at 1.5kg and the lighter one at 1.0kg. neglect friction. the heavy cart starts at rest. you push the lighter cart so that it rolls towards the heavier one at a constant speed of 0.75m/s. in reality, there is some friction between the track and the track. a. how will friction affect the speeds of the two carts after the collision ? will the carts speed be faster, slower, or the same as it was in the friction less case? b. how will friction affect the magnitude and direction of each individual carts momentum after the collision- will the momentum be higher, lower, or the same? explain. c. how will friction affect the systems momentum after the collision-will the momentum be higher, lower, or the same? explain.

Explanation / Answer

the will be slower due to loss of kinetic energy during the collision the direction will be the same but the magnitude will be lesser the momentum will be slower as opposite momentums are added up , and resulted in a loss of KE, inturn reducing the momentum
