Two identical carts-a and b-initially are moving on frictionless air tracks. the initial speed of cart a is twice that of cart b. you then exert the same constant force on the two carts over 1 second. one second later, the change in momentum of cart a is a) non-zero and twice the change in momentum of cart b b) non-zero and the same as the change m momentum of cart b c) zero d) non-zero and half the change in momentum of cart b e) not enough information to determine
