Question

A meteor streaking through the night sky is located with radar. At point A its coordinates are (5.60km, 1.30km ), and 1.20s later its has moved to point B with coordinates (6.20km , 0.925km ).
Part C Find the magnitude of its average velocity between these two points.   v =   km/s   SubmitMy AnswersGive Up Part D Find the direction of its average velocity between these two points.   ?=   ? counterwise from +xaxis.

Explanation / Answer

a)Vx =(6.2-5.6)*10^3/1.2 =500 m/s

Vy =(0.925-1.3)*10^3/1.2 =-312.5 m/s

V=sqrt[Vx^2+VY^2] =0.59 Km/s

b)

theta =tan^-1(Vy/Vx) =-32 degrees
