1. The problem statement, all variables and given/known data Annie uses her 1.50 x104 N Subaru wagon to drag a 2.00 x 103 N crate of mulch from the nd of her driveway. She uses a rope to attach the crate to the rear bumper of her wagon and she configures this connection so that her car will exert a horizontal force on the crate. She then gets into her car and accelerates it (and the crate) forward a steady rate of 2.00 m/s2. While Annie is thus dragging the crate along her driveway, a steady 1200 N frictional force acts on the crate, opposing its motion. 2. Relevant equations Questions I'm having difficulty are: 1. The magnitude of the overall force which the ground exerts on Annie's car equals _____ (the answer is 1.57 x 104 N) 2. The overall force which the ground exerts on Annie's car is directed _____ (answer is above the positive x direction) 3. The attempt at a solution 1. I would assume I need to add the weight of Annie's car and add that to the weight of the crate both which I get a combined 17000 N. This value does not match the correct answer. 2. I cannot find the answer to #2 until I have found the value for #1. From then on, I do not know how to figure it out. Please help me! Thanks!
