Problem 1 A car has an initial velocity of -12 m/sec and acceleration of 5 m/sec 2. Express mathematically, its position as a function of time. x(t) = x o + v o t + (1/2)at 2 x(t) = 0 -12t + 5t 2.

Problem 2 An object is thrown down with a speed of 7 m/sec from the top of the Eiffel tower (300 m high). Express mathematically its position as a function of time. y(t) = x o + v o t + (1/2)at 2 x(t) = 300 - 7t - 4.9t 2.
