1. What is the average speed of a car that travels 25 m in 10. s ?
2. What is the average speed of an object that travels 6.00 m north in 2.00 s and then travels 3.00 m east in 1.00 s ?
3. The average speed of a plane was 600 km/h. How long did it take the plane to travel 120 km ?
4. An object is accelerated uniformly from rest to a speed of 25 m/s in 10. s. The acceleration of the object is
5. As the time required to accelerate an object from rest to a speed of 4 m/s decreases, the acceleration of the object
6. An object originally at rest is uniformly accelerated along a straight-line path to a speed of 8.0 m/s in 2.00 s. The acceleration of the object is
7. The time-rate of change of displacement is
8. A cart initially traveling at 10. m/s to the right is accelerated uniformly at 2.0 m/s^2 to the right. How long will it take for the cart's speed to be 20. m/s ?
9. As an object falls freely near the Earth, its acceleration
