Explanation:
It is given that,
Mass of a box car,
Initial speed of a box car,
Initial speed of another stationary car is 0 as it was stationary
Mass of another box car is 10,000 kg
Let V is the speed of the cars just after the collision. It is based on the concept of inelastic collision. So, using the conservation of linear momentum we get :
So, the speed of the cars just after the collision is 0.875 m/s.
Part 1: V = gt = 10(11) = 110 m/s
Part 2: Vavg = V/2 = 110/2 = 55 m/s
Part 3: d = Vavg(t) = 55(11) = 605 m
