A 2.75kg laptop computer is dropped onto the floor from a height of 1m. assuming that the laptop starts from rest, that it rebounds off the floor up to a height of 5cm, and that the contact with the floor up to a height of 5cm, and that the contact with the floor lasts 10^-3 s, determine the impulse provided by the floor to the laptop and the average acceleration to which the laptop is subjected when in contact with the floor(exress this result in terms of g, the acceleration of gravity).
