is required to stop the car in 242 ft? To find out, carry out the following steps. (1) Solve the following initial value problem. d²s dt² = -k (k constant), with ds dt = 44 and s=0 when t = 0 ds (2) Find the value of t that makes = 0. (The answer will involve k.) dt (3) Find the value of k that makes s=242 for the value of t found in the step (2).
