JUZU-ZUZI BLIVE C)
14. A wheel rotating about a fixed axis at 30 rpm is uniformly accelerated
for 50 seconds during
which time it makes 40 revolutions. Find angular acceleration in rad/sec2 *
(1 Point)​

Answer 1

Answer:

t=5s and θ=50rev

initial angular speed ω

o

=0

Comparing with linear motion s=

⟹α=

5

2

2×50

⟹α=4rev/s

2

Again comparing with v=u+at and u=0

ω=α×t=4×5

⟹ω=20rev/s
