A teacher sends her students on a treasure hunt. She gives the following instructions:

1. Walk 300 m north
2. Walk 400 m northwest
3. Walk 700 m east-southeast and the treasure is buried there.
As all the other students walk off following the instructions, Joe physics student quickly adds the displacements and walks in a straight line to find the treasure. How far and in what direction does Joe need to walk?
A)

187 m in a direction 67.3° north of east
B)

481 m in a direction 40.9° north of east
C)

399 m in a direction 52.5° north of east
D)

284 m in a direction 28.2° west of north
E)

The treasure position cannot be reached in one straight walk.

A car is traveling north at 20.0 m/s at time t = 0.00 s. The same car is traveling north at 24.0 m/s at time t = 8.00 s. What statement is necessarily true about the acceleration of the car?

A) The car undergoes constant acceleration of 0.500 m/s2 during the time from t = 0.00 s to t = 8.0 s. B) The car undergoes constant acceleration of 4.00 m/s2 during the time from t = 0.00 s to t = 8.0 s C) The car has zero acceleration during the time from t = 0.00 s to t = 8.0 s D) The average acceleration of the car is 0.500 m/s2 during the time from t = 0.00 s to t = 8.0 s E) The average acceleration of the car is 4.00 m/s2 during the time from t = 0.00 s to t = 8.0 s
