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 Part D Find the direction of its average velocity between these two points. ?= ? counterwise from +xaxis. 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 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 v = km/s v = km/s Part D Find the direction of its average velocity between these two points. ?= ? counterwise from +xaxis. Part D Find the direction of its average velocity between these two points. ?= ? counterwise from +xaxis. ?= ? counterwise from +xaxis. ?= ? counterwise from +xaxis. v = km/s
Explanation / Answer
distance=sqrt[(6.2-5.6)^2+(1.3-0.925)^2] =0.701 km
vel= 0.701/1.2=0.59 km/s.
