1. a record is turning at the rate of 33 r.p.m. when the 45 r.p.m. button is pressed. The reocrd turns through 1.30 revolutions while speeding up from 33 r.p.m. to 45 r.p.m.

a.) what is the angular acclereration of the record?

b.) how long does the record take to speed up from 33 to 45 r.p.m.?

2. a coin is placed on the record from the above problem, at a distance of 5.75 cm from the axis of rotation. what was the radial (centripetal acceleration of the coin when the record was turning at a rate of 37 r.p.m.?
