2. A hiker walks along the city streets 10 km north, then km east. What is the magnitude of the resulting displacement vector?
3. A hiker walks along the city streets 6 km north, then 10 km east. What is the direction of the displacement vector in degrees counter clockwise from east?
4. A basketball is launched with an initial speed of 10.0 m/s and follows the trajectory shown. The ball enters the basket 0.50 s after it is launched. What are the distances X?
5. Irina standing on the edge of a cliff throws a stone at 40 degree angle above the horizontal with an initial speed pf 10.0 m/s. The instant before the stone hits the ground below. It is traveling at a speed of 57/s. If Irina were to throw the rock at a 40 degree angle below from the horizontal, from the cliff instead , with the same initial speed of 10.0 m/s, what is the magnitude of the velocity of the stone just before it hits the ground? Ignore any effects of air resistance.
6. A rock launched with an initial velocity of 121 m/s at an angle of 15 degrees above the horizontal at time t0. At what time does the protective take to reach its maximum height?
