Lines 1. An airplane lands on a runway. Its velocity after f seconds from landing is given by v(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/s2. The velocity of the plane is measured as in the table below. Velocity (u) Time (t) 110 m/s 5 5 55 m/s 15 s (a) Use the data to determine the initial velocity vo and acceleration a of the plane. (b) Give the equation of the line for the velocity of the airplane
