Suppose that a car traveling with constant speed to the west takes a 90° left turn toward south. which of the following statements about its acceleration in the midpoint of the turn is correct? flag question select one: a. the acceleration is toward the north-west. b. the acceleration is toward south. c. the acceleration is toward the south-east. o d. since the speed s constant the acceleration is zero

a ) The acceleration is towards the north west .

Explanation:

Let v be the magnitude of velocity . Since car is going towards the west ( in - ve x direction ) we can represent it as vector form as follows

initial velocity u  = - v i

Then it turns towards south ( - ve y direction ) so it can be represented as follows

Final velocity = - v j

Change of velocity

= Final velocity - initial velocity

= - v j - (- v i )

Acceleration x time  =  v i - v j

It this vector makes angle θ with positive x axes

Tan θ = - v / v = -1

θ = 135 degree

Therefore acceleration is towards north west.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
