. When we estimate distances from velocity data, it is some-
times necessary to use times fo, f1, fz, fz, ... that are not
equally spaced. We can still estimate distances using the
time periods At; = ti – ti-1. For example, on May 7, 1992,
the space shuttle Endeavour was launched on mission
STS-49, the purpose of which was to install a new perigee
kick motor in an Intelsat communications satellite. The
table, provided by NASA, gives the velocity data for the
shuttle between liftoff and the jettisoning of the solid
rocket boosters. Use these data to estimate the height
above the earth's surface of the space shuttle Endeavour,
62 seconds after liftoff.
