A particle is moving in a circular path with a radius of 2 m and a velocity of 4 m/s. What is the centripetal acceleration of the particle?
Correct: D
The centripetal acceleration of the particle can be calculated using the formula a_c = v^2 / r, where a_c is the centripetal acceleration, v is the velocity, and r is the radius. Given v = 4 m/s and r = 2 m, we can calculate a_c = (4)^2 / 2 = 16 / 2 = 8 m/s^2.
