Will give brainliest need help A car starts from rest and accelerates to a speed of 90 m/s in 16 seconds. What is the acceleration of the car?

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

the answer is 12 as i may remember
