Here we know that the initial velocity of the car is given by:
And the final velocity of the car is given by:
It took 3 seconds to attain the final velocity, so we have
Therefore, the acceleration can be obtained by:
Plugging the values of the initial, final velocity and the time, we get:
So the acceleration of the car is given by:
Now we need to find the direction of the average acceleration of the car:
Here, x and y are the coefficients of the 'x' and 'y' components of the vector:
Therefore, the direction of the average acceleration of the car is .
1) triangle qtr and triangle ate are congruent ( you can say asa or sss). In is specie example you can write either of these.
You can write asa because we are given two angles that are congruent and a side that is shared by both triangles ( which is side qt).
You can write sss because we are given two sides that are congruent and a side that's shared by both triangles ( which is side qt)
2) triangle abc is congruent to triangle def ( you can say asa)
Hope this helps ;)
