A flea stands on the end of a 1.0 cm long

Physics
1 answer:
Snezhnost [94]3 years ago
5 0

Answer:

The rotation speed, w, is 2*pi radians/60 seconds = 0.105 rad/s and r = 0.01 m

The flea needs centripetal force given by

Fc = m*w^2/r

That force must come from friction given by

Ff = mu*N = mu*m*g

So

m*w^2/r = mu*m*g

Substitute the data, cancel the m's, and solve for mu.

5 A photographer runs away from an angry rhino toward the safety of her Jeep What will happen? (Speeds and distances are shown b
irinina [24]

Answer:

A. The photographer will get to the jeep before the rhinocerous

Explanation:

Δv =  Δd/Δt

we can rearrange for time

Δt = Δd/Δv

For the photographer:

Distance is 10m and moves at 6m/s

Δt = 10m/6m/s

Δt = 1.67s

For the rhinocerous

Distance is 16m and moves at 8m/s

Δt = 16m/8m/s

Δt = 2.00s

The distances were to get to the jeep, the photographer makes it to the jeep in a shorter amount of time than the rhino
