WebNov 15, 2024 · There are two forces acting on the bear: its weight W, pulling downward, and the frictional force Ff, pulling upward. Therefore, the net force is given by the … WebDiscuss how “constant velocity” is the key to your answer. A 400-kg bear grasping a vertical tree slides down at constant velocity. What is the friction force that acts on the bear? …
WebWhat is the friction force that acts on the bear? The bear whose mass is 400 kg has a downward weight of 4,000 N since. W = m g = (400 kg)(10 m/s 2) = 4,000 N. Since the bear slides down at constant velocity (or … WebThe force of static friction F s F_s F s F, start subscript, s, end subscript is a force between two surfaces that prevents those surfaces from sliding or slipping across each other. This is the same force that allows you to …
WebJun 13, 2024 · The friction force between the tree and the bear is 3000 N. The acceleration is 0 since the bear slides down at a constant velocity. The sum of the forces is 0. Thus; Upward friction + downward weight = 0 F-mg = 0 F = mg F = (300 kg) (10 m/s² the acceleration due to gravity) F = 3000 N frictional force
