A car moving in a straight line starts at x = 0 at t = 0. It passes the point x = 25.0 {rm m} with a speed of 12.5 {rm m/s} at t = 3.00 {rm s}. It passes the point x = 385 {rm m} with a speed of 47.0 {rm m/s} at t = 20.0 {rm s}.Find the average velocity between t = 3.00 {rm s} and t = 20.0 {rm s}.Find the average acceleration between t = 3.00 {rm s} and t = 20.0 {rm s}.
