Sketch the following speed-time graphs:
determine the:
- acceleration of the objects
- distance travelled
1. a car travels at a steady(constant) speed of 65 km/h for 3 hours.
2. a boy runs from rest and steadily accelerates to a speed of 10 m/s within 5 seconds.
3. a motorcycle accelerates steadily from 12 m/s to 24 m/s over a period of 6 seconds.
4. car decelerates steadily from a speed of 54 km/h until it stops 6 seconds later.
