Question
Problem 6.68 Part A The problem show a free-body diagram. Suppose F 24 N Eigure 1) Choose a correct realistic dynamics problem for which this is the correct free-body diagram. O A1.0 kg rock is pushed by a man with a force of 4.9 N is sliding on an ice surface with a coefficient of kinetic friction 2.4. How long does it take the rock to move 1.0 m? A 30 kg cupboard is being pulled across a room by a string, starting from rest, with the force of 4.9 N. A coefficient of kinetic friction is 2.4. How long does it take the cupboard to move 1.0 m? Starting from rest a 1.0 kg block is pulled across a level surface by a string. The string has a tension of F friction is 0.50. How long does it take the block to move 1.0 m? 24 N, and the block's coefficient of kinetic Starting from rest a man pushes a kid in a sled with the force of F- 24 N. Total mass of a kid and a sled is 30 kg. The coefflicient of kinetic friction between snow and a sled is 0.50. How long does it take the man to move the kid 1.0 m? Submit My Answers Give Up Part B This question will be shown after you complete previous question(s). Figure 1 of 1 Provide Feedback Continue 9.8 N 4.9 N 9.8 NExplanation / Answer
Answer:
Starting from Rest, a 1 Kg Block is pulled across a level surface by a string. The String has a Tension of F = 24 N, and the blocks coefficient of kinetic Friction is 0.5.
Reason: It is clear that a Force of 24 N is applied towards right in figure. Also Since mass is 1 Kg, Weight acting downwards is mg i.e. 9.8 N, and Friction = coefficient of friction x Normal Force = 0.5 x 9.8 = 4.9 N
