sebuah gerinda berputar dengan kecepatan 180 putaran setiap 6 menit.jika jari jari gerinda 10cm berapa kecepata linier dan percepatan sentripetal suatu partikel

180 putaran/6menit = 30putaran/menit

30rpm = 30x2/60phi = 1 phi rad/s

v = w.r
v = 1phi rad x 0.1 m
v = 10phi m/s
v = 10 x 3.14 m/s
v = 31.4 m/s

as = w^2.r
as = (10phi)^r x 10
as = 100phi^2 x 10
as = 100 x 3.14 x 3.14
as = 10 x 9.8596 x 10
as = 985,96
