At the airport, you pull a 16 suitcase across the floor with a strap that is at an angle of 41 above the horizontal
Find the normal force.
Find out the tension in the strap, given that the suitcase moves with constant speed and that the coefficient of kinetic friction between the suitcase and the floor is 0.40.
One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26.
An astronaut travels to an alternate universe that contains infinite charged plane and no other charged objects. The astronaut observes that the electric field in this universe has a magnitude of 1.20 N/C everywhere and points directly away from the ..
A flight attendant pulls her 63N flight bag a distance of 308m along a level airport floor at a constant velocity. The force she exerts is 45N at an angle of 57° above horizontal. Find the work she does on flight bag.
How to find the magnetic field
A bug crawls outward from the center of a compact disc spinning at 160 revolutions per minute. The coefficient of static friction between bug's sticky feet and disc surface is 1.10.How far does the bug get from the center before slipping.
person walks 25.0° north of east for 3-km. How far would another person walk due north and due east to arrive at the equal location?
Assume that the cell is floating on the surface of water, and that the water surface has a coefficient of friction of u=0.300. You now want to use a laser to move cell horizontally, along the surface of the water.
A rocket moves upward, starting from rest with an acceleration of 33.4 m/s2 for 3.47 s. It runs out of fuel at the end of the 3.47 s but does not stop. How high does it rise above the ground.
How much work done against force of gravity
What is the magnitude
A spring has a force constant of 323 N/m and an unstretched length of 6 cm. One end is attached to a post that is free to rotate in the center of a smooth table, as shown in the top view below. The other end is attached to a 4-kg disk moving in un..
A 5kg steel ball strikes a wall with a speed of 8m/s at an angle of 60.0° with the surface. It bounces off with the similar speed and angle. If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ..
