2)a velocity vector has components 36 m/s westward and 22 m/s northward. what are the magnitude and direction of this vector?

The magnitude:
 →
| a | = √ ( 22² + 36² ) = √ ( 484 + 1296 ) = √ 1780 = 42.19 m/s
The direction:
tan α = 22/36 = 0.61111
α = tan^(-1) 0.61111 = 31.43 ° = 31° 26`

The magnitude is 42.19 m/s and the direction is 31° 26`north from west.

Some type of thing that was invisible

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
