A railway wagon of mass m = 5000 kg, moving with velocity t] strikes a viscously damped buffer. The equation of motion is given by d m+co= {it Find the velocity of the truck at time t = 4.2 s, using Eulei's method with a step size t 2 0.7 sr c = 28?5.0 kgg's and initial velocity on 2 am) 2 2.1] ms. Fill in the blank spaces in the following table. Round up your answers to 4 decimals. 1:1:me velocity] Which of the following would make Euler's solution {that you just obtained} more accurate? 1 taking step size at = 1.35 2 taking step size at = 0.38s 3 Euler's solution cannot be improved Type your answer (1, 2, or 3} here
