A hummingbird flies in circles around a bush. if the velocity of the hummingbird is 720 cm/s and the radius of the circular path is 9.0 cm, what is the centripetal acceleration of the hummingbird?

When Kevin pulls his cotton shirt off his body, the electrons get transferred from the (shirt or body) to the (shirt or body). So, the shirt becomes (positively or negatively) charged and Kevin's body becomes (positively or negatively) charged.

The acceleration function (in m/s2) and the initial velocity are given for a particle moving along a line. a (t) = t + 6, v (0) = 3, 0 ≤ t ≤ 11 (a) Find the velocity at time t. v (t) = Correct: Your answer is correct.
