You’re riding your bicycle first west a distance of 10.6 km, then south a distance of 14.1 km. |
| (a) |
In what direction does your average velocity vector point, in degrees south of west? |
||
| (b) |
If the total trip took 10.3 minutes, what is the magnitude of this average velocity, in m/s? |
Homework Answers
a)
direction
x = arctan ( 14.1 / 10.6)
x = 53.07
=======
b)
net displacement
d^2 = 14.1^2 + 10.1^2
d = 17.344 m
av velocity = d /t = 17.344 / ( 10.3* 60)
v = 0.028 m/s
======
Comment before rate in case any doubt, will reply for sure.. goodluck
