r = 0.04m
1265 rev/min
a.)(1265revminute)(1min60sec)(2πradrev)=132.47radsec
ω=132.47radsec
b.) The linear speed is called the tangential velocityalso
Vtan=rω
Vtan=(0.022)(132.47)
Vtan=2.914ms
c.)acent=rω2
acent=(0.04)(132.47)2
acent=701.9ms2
d.)Vtan=rω
Vtan=(0.04)(132.47)
Vtan=5.299ms
D=VT
D= (5.299)(1.96)
D= 10.386 m
