1. The problem statement, all variables and given/known data A particle moving at a velocity of 5.2 m/s in the positive x direction is given an accelera- tion of 5.3 m/s2 in the positive y direction for 9.9 s. What is the final speed of the particle? Answer in units of m/s 3. The attempt at a solution I multiplied the acceleration by the time to get velocity. I found the resultant velocity between the two vectors which was 52.7. Is that the same as the final speed?
