Since there is no resisting force(air resistance etc.), the tension in the cable/joint between the engine and the carriage will be the net force.
this is responsible for accelerating both the carriage and the 'caboose'
Fnet = T = ma.
'm' is the sum of the masses of the 'caboose' and the...
Well the simplest way is to find factors of -40. Replace each in the original expression one by one and when the result is zero: Bingo! You've found a root. In this case 10 is one root. next, divide the original expression by x-r (r = root found by trial and error) to get a quadratic equation...
