A particle starts from the origin at t = 0 with an initial velocity having an x component of 20:7 m/s and a y component of -16:3 m/s. The particle moves in the xy plane with an x component of acceleration only, given by 5:03 m/s2.(adsbygoogle = window.adsbygoogle || []).push({});

A)Determine the x component of velocity after 9:01 s. Answer in units of m/s.

B)Find the speed of the particle after 9:01 s.

Answer in units of m/s.

I have found the answer to A as 66.02 but for B isn't the answer 66.02-(-16.32)= 82.32?
