Two cyvlists are having a race along a straight road. Bradley starts 50m ahead of chris. Bradley starts from rest, accelerates to 15m/s in 10s and remains at this speed for 40s before decelerating at 0.5m/s^2. Chris starts 5s later than Bradley. He starts from rest, accelerates to 16m/s in 8s and maintains this speed. a) show that Bradley is still ahead when he starts to slow down, and find how far ahead he is. b) Find the amount of time Bradley has been cycling when he is overtaken by Chris.

Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –
