A woman exerts a constant horizontal force on a large box. As a result, the box moves across a horizontal floor at a constant speed "v0". The constant horizontal force applied by the woman:
has the same magnitude as the weight of the box.
is greater than the weight of the box.
has the same magnitude as the total force which resists the motion of the box.
is greater than the total force which resists the motion of the box.
is greater than either the weight of the box or the total force which resists its motion.
If the woman in the previous question doubles the constant horizontal force that she exerts on the box to push it on the same horizontal floor, the box then moves:
with a constant speed that is double the speed "v0" in the previous question.
with a constant speed that is greater than the speed "v0" in the previous question, but not necessarily twice as great.
for a while with a speed that is constant and greater than the speed "v0" in the previous question, then with a speed…

- In order to straighten a crooked tree, a rope is attached horizontally from the top of the tree to a nearby building. A force of 600 N is applied downward at the center of rope. The angle between this downward force and the rope going to the tree is 95 degrees, which is the same as the angle between the downward force and the rope going to the building. The tension in the rope going to the tree is 300 N. 600 N. 1200 N. 3442 N.arrow_forward2) Suppose you put an object on an inclined slope and let go. If there is enough friction between the object and the surface of the slope, it might not go anywhere. This can be important when figuring out what kind of tires you need so you don't slip on an icy hill! Whether there is friction or not, it is useful to be able to write the gravitational force acting on the object as the sum of two perpendicular vectors: one parallel to the surface of the slope, and one perpendicular to the surface of the slope. For this series of questions, suppose the inclined slope is fixed at an angle of 30° and the object has a mass of 3 kg, as shown in the diagram. 30° 3 kg. a) Gravitational force has a magnitude equal to an object's mass times acceleration due to gravity, and a direction of "straight down." Since we are using kilograms, acceleration due to gravity should be given in meters per second squared, and the value is approximately 9.8 m/s².
