A particle is moving clockwise in a circle of radius 1.75 m. At a certain instant, the magnitude of its acceleration is
a =
a
= 39.0 m/s2,
and the acceleration vector has an angle of θ = 50° with the position vector, as shown in the figure. At this instant, find the speed,
v =
v
,
of this particle.
