Fantastic news! We've Found the answer you've been seeking!
Question:
(a) Directed toward the centre of the circle.
(b) Equal to v2/R.
(c) Equal to the time rate of change of the velocity vector.
(d) All of the above are true.
2. If a particle moves in a circle of radius (R = 1.35m) at a constant speed of
(v = 6.70m/s), what is the magnitude and direction of its centripetal acceleration
(ac)?
3. If the mass (m) of the particle in question 2 is 0.350 kg, what is the magnitude and
direction of the centripetal force (Fc) on it?
4. A 0.500 kg particle moves in circle of radius (R = 0.150m) at constant speed. The
time (t) for 20 complete revolutions is 31.7s. What is the period (T) of the motion?
What is the speed (v) of the particle?
5. What is the centripetal acceleration (ac) of the particle in question 4? What is the
centripetal force (Fc) on the particle?
