Brooklyn is preparing for the upcoming rugby season. To develop some strength and power, she is training out on the turf with a weighted sled. Brooklyn is pushing the sled with a force of 200 N and this push force is directed 25 degrees downwards or below the horizon. Brooklyn applies this force for 3 seconds and the 55 kg sled was initially at rest when Brooklyn began applying the push force. The coefficient of dynamic friction between the sled and the turf on which the sled was sliding was 0.20. a) What will be the velocity of the sled in m/s immediately after the 3 seconds?  b) What will be the momentum of the sled be immediately after the 3 seconds? c) After the 3 seconds, Brooklyn slips and is no longer able to apply the 200 N force to the sled. From the moment that Brooklyn slips, how far (in meters) will the sled continue to slide before
