Exercise 1:1. A biker travels at an average speed of 18 km/h along a 0.30 km straight segment of a bike path. How much time does the biker take to travel this segment?2. A hiker travels south along a straight path for 1.5 h with an average speed of 0.75 km/h and then travels north for 2.5 h with an average speed of 0.90 km/h. What is the hiker's displacement for the total trip?3. A stroller walks the first half of a straight 1.0 km trail at a steady pace of 0.75 m/s, east. He walks the second half at a constant stride of 0.60 m/s, east. What is his average velocity along the trail?4. A shopping cart is given an initial velocity of 2.0 m/s and undergoes a constant acceleration of 3.0 m/s2. What is the magnitude of the cart's displacement after the first 4.0 s of its motion?5. A skater glides off a frozen pond onto a patch of ground at a speed of 1.8 m/s. Here she is slowed at a constant rate of 3.00 m/s2. How fast is the skater moving when she has slid 0.37 m across the ground?6. A sports car traveling at 27.8 m/s slows at a constant rate to a stop in 8.00 s. What is the displacement of the sports car in this time interval?7. A toy car is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 2.0 m/s2. What is the final velocity after 6.0 s?8. A soccer ball is moving horizontally at a speed of 3.0 m/s. It then undergoes a constant negative acceleration. After 4.0 s, the ball is moving at 1.5 m/s. What is the ball's displacement?9. A
