Question

A crate is sliding down an inclined ramp at a constant speed of 0.55 m/s. The vector sum of all the forces acting on this crate must point down the ramp

Answer 1

`F_(net) = 0`

Step-by-step explanation:

here it is given that the crate is sliding down with constant speed

so we will have

`v = constant`

now we can say

`a = (dv)/(dt)`

so here we have

a = 0

now from Newton's II law we can say that sum of all forces on the system is always product of mass and its acceleration

so here we will have

`F_(net) = ma`

`F_(net) = 0`
