Using formula V^2=(V(0))^2+2*a*s where a is acceleration, s is displacement, v is velocity, V(0) is initial velocity: 80^2=50^2+2as (1) M^2=50^2+(1/2)*2*as (2) where M is the velocity at halfway Solved them simultaneously and got M=5*sqrroot(178)

Homework Statement A train at constant acceleration is traveling in a straight line. It passes two points at a velocity of 50km/h and 80km/h respectively. What is the exact velocity of the train when it is halfway between these two points? Let v be the exact velocity of the train when it...
