V PartA An object with cross section A is shot horizontally across frictionless ice. Its initial velocity is vox at to = 0 3. Air resistance is not negligible. Express your answer in terms of the variables vox, C, p, A, m, and t. Find the expression for the velocity at time t. } View Available Hint(s) A2 V Part5 A 1.3 m wide, 1.4 m high, 1600 kg car with a drag coefficient of 035 hits a very slick patch of ice while going 21 m/s . Air resistance is not negligible If friction is neglected, how long will it take until the car's speed drops to 11 m/s 17 Express your answer in seconds.
