What is its top speed in km/h? 5. A tree sloth is the slowest moving animal. Walking as fast as it can, it covers 4 meters in 1 minute. What is its top speed in m/s? 6. How long would the tree sloth take to walk at top speed 274 m? . What is the average velocity of a car that moved 60km Southeast in 3 hours? In m/s? 8. What is the average velocity of a car that moved 40 km East and 80 km West in 2 hours? 9. Acceleration is the measure of the change in what? 10. If a car accelerates from 3 m/s to 12 m/s in 3 seconds, what is the car’s average acceleration? 11. How long does it take to accelerate an object from rest to 15 m/s if the acceleration was 3 m/s2? 12. If a car has a constant acceleration of 4 m/s2, starting from rest, how fast is it traveling after 5 seconds? 3. If a car has a constant acceleration of 4 m/s2, starting from rest, how far has it traveled after 5 seconds? Working with SUVAT equations Remember to always sketch a diagram and write down the known values of s, u, v, a and t. v=at + u s= ? (u+v) t s=ut + ? at2 v2=u2 + 2sa 1.
