2/231 A particle moving in the x-y plane has a veloc-
ity v = 7.25i +3.48j m/s at a certain instant.
If the particle then encounters a constant accel-
eration a = 0.85j m/s², determine the amount of
time which must pass before the direction of the
tangent to the trajectory of the particle has been
altered by 30°.
