Edge 2020

Answer 2

Answer:

B and C

Step-by-step explanation:

Angular velocity

Gear 1:

w = theta/t

w = $\frac{60 rev}{min} * \frac{1 min}{60 sec} * \frac{2\pi }{rev}$  =  2 $\pi$

Gear 2:

w = $\frac{80 rev}{min} * \frac{1 min}{60 sec} * 2\pi$ = 2.66 $\pi$

Linear Velocity

v = w r

Gear 1:

2 pi * 6 = 12 $\pi$

Gear 2:

2.66 pi * 4 = 10.64 $\pi$
