Question

A train moves at a constant speed of 60km/h towards east for 30 minutes then in a direction of 30 degrees east of due north for 20 minutes and then west for 45 minutes what are the



a.Magnitude in km/h



b.Angle of average velocity

Answer 1

$\sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{ \sqrt{?} } } } } } } } } }$

Answer 2

Answer:

magnitude (km/hr) =sq.root13/19

angle of average velocity=tan^-1(-2sq.root3)
