Abicycle travels 6.10 km due east in 0.210 h, then 11.30 km at 15.0° east of north in 0.560 h, and finally another 6.10 km due east in 0.210 h to reach its destination. the time lost in turning is negligible. assume that east is in the +x-direction and north is in the +y-direction. what is the direction of the average velocity for the entire trip? enter the answer as an angle in degrees north of east

Explanation:

Given

First bicycle travels 6.10 km due to east in 0.21 h

Suppose its position vector is

After that it travels 11.30 km at east of north  in 0.560 h

suppose its position vector is

after that he finally travel 6.10 km due to east in 0.21 h

suppose its position vector is

so position of final position is given by

t=0.21+0.56+0.21=0.98 h

For direction

w.r.t to x axis

false

explanation:

boats, things on boats luggage are way more heavy then water.
