Here is the question:
A cheetah is moving at 5m/s. It can accelerate at 10m/s^2. How long will it take to increase its speed to 20 m/s?
HEELP!! THANK YOU :)
Acceleration= Change in velocity / Time taken
Put it into a triangle formation;
T=Time takenV=Change in velocity
Put your finger over what you are trying to work out, in this question it is time taken.
You would do Change in velocity/Acceleration
Hope this helps :)
