The dispatcher of courier service receives a message from truck a that reports a position of +5 after a displacement of +2. what was the initial position of truck a? first solve the problem using a number line and then solve the problem using an equation.

The formula we need to use is displacement.

, where xf is final position and xi is initial position.

We report the final position of 5 and the displacement of 2 so the formula is now:

.

So the initial position of truck A is 3.

Hope this helps.

more than, less

less than, more

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
