Yeah, sorry, I didn't write the formula correctly that was given in this exercise.. I edited the OP. distance= z + b*time + x*(time^2) + y*(time^3) z is some distance b is starting speed I have really bad English when it comes to terminology, so I hope you can understand now.

Homework Statement distance= z + b*time + x*(time^2) + y*(time^3) x=0,2m/s^2 y=0,15m/s^3 I have to calculate after how long time the speed has increased by 10 m/sThe Attempt at a Solution I have no idea what to do with m/s^3
