Renee is on Spring Break and pulling her 21-kg suitcase through the airport at a constant speed of 0.47 m/s. She pulls on the strap with 120 N of force at an angle of 38° above the horizontal. Assume the ground to be flat, Draw a FBD showing the forces on the suitcase. Find the acceleration of the suitcase. Determine the normal force experienced by the suitcase. Determine the total resistive force (friction) experienced by the suitcase. Find the coefficient...
The car shown in the figure has mass m(this includes
the mass of the wheels). The wheels have radius r, mass
mw, and moment of inertia
I=kmwr2. Assume that the axles
apply the same torque ? to all four wheels. For
simplicity, also assume that the weight is distributed uniformly so
that all the wheels experience the same normal reaction from the
ground, and so the same frictional force.
Part A
If there is no slipping, a frictional force must...

The coefficient of kinetic friction between a suitcase and the floor is 2.30, if the suitcase has a mass of 71.5 kg how far can it be pushed across the level floor A 0 35 kg pinecone falls 16 3 m to the ground, whore.t lands with a speed of 12 m/s. With what speed would the pinecone have landed If there had been no air resistance? Did air resistance do positive work, negative...
B. An 18kg sack of apples is lying on the ground. The coefficients of friction between the ground and the bag are mu_s = 0.6 and mu_k=0.4. An old lady grabs the bag of apples and begins pulling it diagonally upwards with a force of 100N, at an angle 60 degrees above the horizontal i. Draw a regular diagram (drawing) and a System Schema for the situation ii. Draw a pure FBD and a component FBD of the sack of...

What horizontal pull is need to keep the wagon rolling in a straight line at 2.00 ft/s? 2. A wagon weighs 50.0 N, and the coefficient of rolling friction between the wheels and the level floor is 0.150. What horizontal pull is need to keep the wagon rolling uniformly?
The car shown supports it the total weight and the rear tire carries 60%. The car is on an incline having an angle o( with the horizontal X-axis. The coefficient of friction between the tires and ground is μ Given that W-3500 lbs and H 0.35 s weight "W" on its tires such as the front tire cames 40% of a) If both tires are locked with brakes, what is the maximum angle oc of the incline such as the...

The diagram below is a top-down view of two children pulling a 12. 6-kg sled along the snow. The first child exerts a force of [F1|-10.0 N at an angle θ,-45.0° counterclockwise from the positive x direction. The second child exerts a force of [F21-6.00 N at an angle θ2 = 30.0° clockwise from the positive x direction. We use a right-handed coordinate system with the +x axis and +z axis in the horizontal plane, and the...
