If there is no friction, the force that moves the box forward horizontally must be matched by the same force.
If there is friction, then the force moving it forward = frictional force + the additional force you need to add.
<span>inclined plane formula is length/hight
so 5/2= 2.5
and work= f x d so
work= 5 x 104 x 10= 5200 W
</span>
<span>Latitude lines mark North and South hemispheres (C), as well as
North and South positions within each hemisphere.</span>
Answer:
The answer is D , none of the above
Explanation:
1600÷8=200s 1200÷90=13.33s 50÷15= 3.33s (1600+1200+50)/(200+13.33+3.33) = 13.15m/s
A moment causes a rotation about or axis. If the moment is to be taken about a point due to a force F, then in order for a moment to develop, the line of action cannot pass through that point...... the total moment was zero because the moment arm was zero as well
