A jet leaves an airport on a bearing of N 77* W and travels for 243 mi. It then turns and continues on a bearing of S 13* W for 104 mi. Find how far the jet is from the airport to 3 decimal places.

physics
Vf=Vi+at Vf=? Vi=19 m/s a=1.8 m/s^2 t=6.8 Vf is what are we are trying to find. So, Vf=(19 m/s)+(1.8 m/s^2)x(6.8s) Vf= 31.24 m/s But because of significant figures, our final answer would be 31 m/s.

math
