... An old “45” vinyl record is meant to spin at 45 rpm. Its diameter is 7 inches (17.78 cm). Suppose that you glue a pea to the edge of the record and spin the record at this frequency. Find the pea’s (a) angular speed , (b) tangential speed, and (c) centripetal acceleration . Now suppose that you glue ...

Question 1 - BrainMass
... magnitude of his average acceleration over this period of time? Answer: Writing in the components form with east as x and north as y directions we have V1 = 18i + 0j and V2 = 0i – 48j hence the change in velocity is V2 – V1 = -18i – 48j whose magnitude is [(-18)2 +(-48)2] = 51.3 km/hr. As this chan ...
