First, you need to learn some basic terms. You probably know about position, distance and time. Use the link to watch a video lesson and find out what displacement, velocity and acceleration are.
Now, let’s solve some related problems.
1. A racecar starts from rest and speeds up uniformly to the right until it reaches a maximum velocity of 60 m/s in 15 seconds.
What is the acceleration of the racecar?
Answer using a coordinate system where rightward is positive.
