Apuntes

1. During training, an athlete ran 50m at a constant speed of 2.5m/s from the starting point. Then they rested for 10 seconds before jogging back at a constant speed to the starting point in 30 seconds. Draw a distance-time graph to show the athlete’s journey. 2. Malakai and Josef walk from Point A to Point C. Malakai walks the following route, A → B → C. While Josef walks from A → C directly. Both boys arrive exactly 30 seconds after leaving Point A. a) Calculate the average speed with space of each boy and determine who was travelling faster. 3. Imagine you are on a straight road. A car passes at v = 15 m/s and you start the stopwatch. a) Make a table showing where the car will be in the next 20 s (take data every 5 s). b) Draw position-time and speed-time graphs. c) Where will the car be when 1 minute has passed? 4. You are told that next week you are going on a trip to a reservoir nearby. You know that the distance to the reservoir is 117 km and that the bus will travel 10 km at 80 km/h, 30 km at 100 km/h, 5 km at 50 km/h and the rest at 110 km/h. How long will it take the bus to reach the reservoir? 5. Indicate which type of movement each graph corresponds to. 6. When Jane dri...
