QuestionA 3 kg object is constrained to move horizontally (so that a y = 0… A 3 kg object is constrained to move horizontally (so that ay = 0 but ax != 0) . There are two forces acting on the object that can make the object move horizontally: A 57 N force that acts up and to the right, 69 degrees above the horizontal, and a 55 N force that acts down and to the right, 35 degreesbelow the horizontal. What is the horizontal acceleration of the object?A 9 kg dog is tired of being on a walk, and decides to lay down. His cruel, impatient owner uses the leash to apply a 25 N force that acts to the right, 31 degrees above the horizontal drag the dog across the ground. This force is enough to drag the dog, so that kinetic friction is acting, but isn’t enough to actually lift the dog off the ground. If the coefficient of kinetic friction between dog and ground is 0.1, calculate the dog’s acceleration in m/s2. In the middle of the night, the dog bites its owner. (Use g = 10 m/s2)Consider a skier on an 91 m long, frictionless slope that makes an angle of 48 degrees with the horizontal. If the skier starts at rest, what is the skier’s speed at the bottom of the slope, in m/s? (Use g = 10 m/s2.)A 8 kg box is pushed across a horizontal frictionless surface by a 192 N force that acts 21 degreesbelow the horizontal. Calculate the acceleration of the box, in m/s2.SciencePhysics SCIENCE 712
