Answer:
The minimum angular velocity of the platform what whould the block slides away is w= 2.26 rad/s.
Explanation:
m= 0.265 kg
r= 2.4 m
μ= 0.257
g= 9.8 m/s²
W= m * g
W= 2.597 N
Fr= μ * W
Fr= 0.66 N
∑F = m * ac
W+Fr = m * ac
(W+ Fr) / m = ac
ac= 12.29 m/s²
ac= w² * r
√(ac/r)= w
w= 2.26 rad/s
Here is just a few:
1. white guys cant jump like black guys therefore white guys shouldn't play basketball
2. men are stronger than women so men should weight lift
3.football is a manly sport therefore woman should not play it
