At the start of a play, Matthews runs downfield at 45 with respect to the 50-yard line and covers 8.0 m in 1 s. He then fins straight down the field at 90 with respect to the 50-yard line for 12 m, with an elapsed time of 1.2 s. (a) What is Matthews’ final displacement from the start of the play? (b) What is his average velocity?A soccer ball is kicked at an angle of 35o and gained an initial velocity of 40 m/s.1. Determine the velocity along x. 2. Determine the range of the projectile. 3.
