2. A spaceship in a videogame is programmed to move following the quantities below where velocity v is in m/s, time t is in seconds, and position vector r is in meters. The spaceship moves at constant acceleration in both axes. The spaceship starts moving from the position (5,-3). f (2t + 5)i + (t- 3)j V = 2ti + (2 + t)j (a) At what position will the spaceship be after 3.5 seconds. (Ans: (17, -2.5)) (b) What will be the velocity of the spaceship at moment it reaches 18.0 m in the x-axis? Express the answer in unit-vector form. (Ans: V = 81 + 4j) %3D

A “moving sidewalk” in an airport terminal moves at 1.0 m/s and is 35.0 m long. If a woman steps on at one end and walks at 1.5 m/s relative to the moving sidewalk, how much time does it take her to reach the opposite end if she walks (a) in the same direction the sidewalk is moving? (b) In the opposite direction?
