While moving in, a new homeowner is pushing a box across the floor at a constant velocity. The coefficient of kinetic friction b
Citrus2011 [14]

Answer:

\theta = 66.7 degree

Explanation:

since force is applied downwards at some angle with the horizontal

so here we will have

F_n = mg + Fsin\theta

now we know that the box will not move if applied force is balanced by frictional force on it

so we will have

Fcos\theta = \mu F_n

F cos\theta = \mu (mg + F sin\theta)

F(cos\theta - \mu sin\theta) = \mu mg

F = \frac{\mu mg}{cos\theta - \mu sin\theta}

so here we can say

cos\theta - \mu sin\theta > 0

tan\theta = \frac{1}{\mu}

\theta = tan^{-1}\frac{1}{\mu}

\theta = tan^{-1}(\frac{1}{0.43})

\theta = 66.7 degree

How does the thickness of wood affect its stability
Law Incorporation [45]

Answer:

Making the lumber thick will make it stiff, which seems good. On the other hand, with thicker lumber, differences in expansion on the two faces have more leverage to make the lumber move.

A dog is 60m away while moving at constant velocity of 10m/s towards you. Where is the dog after 4 seconds?
evablogger [386]
20m away

the dog was 60m away from. you subtract 40m since it is 10m/s x 4 seconds
