Two people pull as hard as they can on horizontal ropes attached to a boat that has a mass of 200 kg. If they pull in the same direction, the boat has an acceleration of 1.59 m/s2 to the right. If they pull in opposite directions, the boat has an acceleration of 0.509 m/s2 to the left. What is the magnitude of the force each person exerts on the boat? Disregard any other horizontal forces on the boat. smaller force N larger force N
A snowmobile climbs a hill at velocity v-up. The slope of the hill is a 2 ft rise for every 70 ft of distance. The resistive force of the snow is equal to 4.12 percent of the weight of the snowmobile. How fast will the snowmobile move downhill, assum..
