Explanation:
Answer:
A. τ = 358 N.m
B. m = 73kg
C. V = 209.5 m/s
Explanation:
Let's first convert angular speed to rad/s:
ω = 4000 rev/min * 2π / 60 = 419 rad/s
Since Power is P = τ * ω,
τ = P / ω = 358 N.m
For part B: On the hanging weight:
T - m*g = 0
T = m*g
On the drum:
τ = T*R Replacing the expression for Tension of the rope:
τ = m*g*R
Solving for m:
m = 73 kg
For part C:
V = ω * R = 209.5 m/s
Answer:
2km/min
Explanation:
Velocity= change in distance / time taken
Velocity = 20km/10min=2km/min south
South is placed there to show what direction she went, as velocity has both magnitude and direction
