A 10 kg block with an initial velocity of 10 m/s slides 10 meters across a horizontal surface and comes to rest after sliding for 2 seconds. How much force was acting on the block to make it stop? Your answer should be in units of N but you should only submit the number for your answer (and don't worry about negative signs, just submit a positive value).
