Subject:PhysicsPrice: Bought3
During 4.0 hour adventure race in the desert, a dune buggy begins at a position 200 km (E 60 degrees S) of the checkpoint. It then drives to a location of 35 km (S) from the checkpoint. Finally, it ends up 85 km (W 25 degrees N) of the checkpoint. Determine both its average speed and average velocity. Draw a diagram.
Equations:
a^2 = b^2 + c^2 - 2bc cos A
cos A= b^2 + c^2 - a^2/ 2bc
¯Vav = ?¯d/?t
¯Aav=?¯v/?t
