Lines 1. An airplane lands on a runway. Its velocity after t seconds from landing is given by u(t) and satisfies the equation v(t) - vo + at, where vo is the initial velocity of the plane (as it touches the ground) given in m/s and a is its acceleration given in m/s?. The velocity of the plane is measured as in the table below. Velocity (v) Time (t) 110 m/s 5 s 55 m/s 15 s (a) Use the data to determine the initial velocity vo and acceleration a of the plane
