Q. As you ride your 14-kg bicycle on level ground you do some work against a 30N force of air resistance if your mass is 65-kg.What is power you apply to maintain a velocity of 25-km`.a-on level ground b-going up a 5degrees slope?(remember it's a numerical please solve this)
Q. A 41 kg box is being pushed a distance of 7m across the floor by a force P whose magnitude is 151-N. The force P is parallel to the displacement of the box. The coefficient of kinetic friction is 0.25. Determine the work completed on the box by each of the four forces that act on the box. Be sure to include proper plus or minus sign for the work completed by each force.
