Can't get right answer (multiple attempts). My work: Since this is a 2 step euler method style question, I first do .1 * .0877 to get change in distance in the first .1 second which results in the position .08857m. I use this and find the spring force. (k constant is 47) so F = -47*(.08857-.22) which gives 6.17721N. Then u subtract gravitational force 9.8x.256 from it to get a netforce of 3.58021N. Then we find impulse or change in momentum by multiplying that force by .1 which gives .358021. We can find final momentum by using the original velocityx weight (.265x.0877 = .0232405) then add on the impulse to get final momentum of (.358021+.232405 = .3812615) then use this final momentum/mass(.265) to get velocity of 1.438722642. Then u multiply that by .1 to get distance covered(.1438722) in 2nd time step and add that to first time step to get answer of .2324422 which i also put in and was wrong
