When we estimate distances from velocity data, it is sometimes necessary to use times to, t1, t2, t3, . . . that are not equally spaced. We can still estimate distances using the time periods At; = t; - t; - 1. For example, a space shuttle was launched on a mission, the purpose of which was to install a new motor in a satellite. The table provided gives the velocity data for the shuttle between liftoff and the jettisoning of the solid rocket boosters. Use these data to estimate the height, h, above Earth's surface of the space shuttle, 62 seconds after liftoff.
