Question

A meteor streaking through the night sky is located with radar. At point A its coordinates are (5.20km, 1.30km ), and 1.18s later its has moved to point B with coordinates (6.24km , 0.920km

part A

Find the x component of its average velocity between A and B.

--------- km/s

Part B

Find the y component of its average velocity between A and B

------ km/s

Part C

Find the magnitude of its average velocity between these two points.

------- km/s

Part D

Find the direction of its average velocity between these two points.

------- ? counterclockwise from +x axis.

Explanation / Answer

a) vx = (1.3 - 0.92)(1000)/1.18

= 322.03m/s to the left

b) vy = (6.24 - 5.2)(1000)/1.18

= 881.36m/s upward

c) v = (322.032 + 881.362)0.5

= 938.35m/s

d) counter clockwise
