1. Two horses are pulling a load. The chains between them are at an angle of 45 degrees to each other. One horse pulls with a force of 260 N, the other with a force of 320 N. a) What is the magnitude and direction of the resultant force? b) What is the magnitude and direction of the equilibrant force? 2. A canoeist who can paddle at 4 km/h in still water wants to cross a 500 m wide river that has a current of 1 km/h. | a) If he steers the canoe in a direction perpendicular to the current, determine the resultant velocity and the point on the opposite bank where he lands. b) If he wishes to travel straight across the river, determine the direction in which he must head and the time it takes to cross the river
