If a car traveling at 75 mph west, changes its direction to east, does its acceleration change? Explain

yes the acceleration changes..

Explanation:

as we know that that acceleration is a vector quantity, hence it changes with the change in either it's magnitude or direction and both and here in this condition the car changes it's direction from west to east hence it changes the direction so the acceleration changes too.

i hope it helped. .

the answer to your question is high voltage and high currency

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
