Question #1 of 3:Rocky McBlock is a receiver for the Kennesaw Kilowatts in Metro Metric Football League.  In this league all distances on the field are measured in meters, and Rocky always runs straight up and down the field (there is no sideways motion - only motion towards and away from the end zone).  Rocky leaves the line of scrimmage when the ball is snapped and runs foward for 12 seconds at a speed of 1.5 m/s.  He catches the ball and continues to run foward for 8 more seconds at a speed of 2.5 m/s.  He is then hit by Big Bobby Clobber of the Marietta Megatons and pushed backwards for 5 seconds at a speed of 0.5 m/s, at which point he is tackled to the ground.  From the time he leaves the line of scrimmage until the time at which he is tackled how far does Rocky traveled?

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 –
