\question At time, t=0, two particles are on the x axis.  Particle A is  (initially) at the origin and moves at a constant speed of 6.27 m/s at an angle of \straighttheta\  above the x-axis.  Particle B is initially situated at x= 2.38 m, and moves at a constant speed of 2.94 m/s in the +y direction.   What is the value of \straighttheta\  (in radians)?
