Question

This figure

represents the total acceleration of a particle moving clockwise in a circle of radius

r = 2.90 m

at a certain instant of time.

(a) For that instant, find the radial acceleration of the particle.
m/s2 (toward the center)

(b) For that instant, find the speed of the particle.
m/s

(c) For that instant, find its tangential acceleration.
m/s2 (in the direction of the motion)

This figure (|a (a) For that instant, find the radial acceleration of the particle. m/s^2 (toward the center) (b) For that instant, find the speed of the particle. m/s (c) For that instant, find its tangential acceleration. m/s^2 (in the direction of the motion) arrow | = 15.5 m/s^2) represents the total acceleration of a particle moving clockwise in a circle of radius r = 2.90 m at a certain instant of time.

Explanation / Answer

tangential acceleration = a sin 30 = 7.75 m/s2.

radial acceleration = a cos 30 = 2.390

velocity, V2/ r = 2.390

V = 2.63 m/s2
