1. A space shuttle deploys a parachute to slow the vehicle when it hits the runway. Suppose that the deceleration can be expressed as = 1.8v2, (1) where v(t) is the speed of the shuttle, measured in kilometers per hour (km/h), at time I. Assume that the shuttle lands at t = 0 with speed 120 km/h. (a) (4 points) What are the units of the coeicient 1.8? Briey justify your answer (no explanation, no credit). (b) (6 points) Rewrite Eq. (1) so that velocity is expressed in units of meters per second (m/s) and acceleration in m/sz, briey justifying your calculations (no explanation, no credit). You do not need to solve this equation for v(t)
