An airplane travels 79 m/s as it makes a horizontal circular turn which has a 787 m radius. What is the magnitude of the resultant force (in Newtons) on the 57-kg pilot of this airplane?

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

Superman is applying a 17,000 N horizontal force to try and stop a speeding locomotive.  This train has a mass of {9004} kg, it is on level, horizontal track, and gravity in Metropolis is 10 N/kg.  The train is originally travelling at 25 m/s, and the brakes have failed. (Friction force is zero).   Draw a Force Body Diagram of the train, labelling and calculating all forces. What is the acceleration of the train? How many seconds does it take for Superman to stop the train? How far does the train travel in that time?

At a certain mining operation, 2400 kg of gravel falls onto a conveyor belt every minute. If the belt is moving at 5.6 m/s, how much horizontal force does the gravel exert on the belt?

A hot air balloon begins to rise from rest. The lift on the balloon due to the buoyant force is 5000 N. In order to minimize the time until the passenger is reunited with their cell phone, what should the horizontal component of the passenger’s velocity be so that they land directly on their phone which is initially 3 m away in the horizontal direction?

A stack of two crates is being accelerated upwards by two cables. The cables are directly attached to crate 1 and the tension in each cable is 3248 N. You may assume that the masses of the cables are negligible compared to the masses of the crates. The acceleration of the crates is? bottom crate crate 1 is 109 kg. the top crate is 248 kg.

A woman pulls a cloth out from under a 200 g bowl sitting on a table. The bowl is 30.0 cm from the far edge of the cloth, and the cloth exerts a friction force of 0.125 N on the bowl. Assume the cloth is pulled with a constant horizontal acceleration of 2.80 m/s2. What distance (in m) does the bowl travel relative to the top of the table? (Assume the cloth moves in the +x-direction and notice that it moves more than 30.0 cm relative to the top of the table.)

A spacecraft flying horizontally over the surface of the moon at an elevation of 1500m with a speed of 350m/s, drops a package with a mass of 1200kg to astronauts on the surface. Use gm= 1.6m/s2 for the acceleration due to gravity on the Moon. a)How long does it take the package to hit the surface after it is dropped? b)How far ahead (distance) of the package’s landing spot should the package be released? c)What is the velocity of the package just before it hits the surface? d)What is the magnitude of the velocity of the package just before it hits the surface of the Moon?

A tractor is speeding up at 3 m/s/s while pulling a 744 kg sled with a rope at an angle of 34 degrees. The coefficient of kinetic friction between the sled and ground is 0.5. What is the tension (Newtons) in the rope? (g=9.8 m/s2)

A robot pushes a 20-kg box on the horizontal surface as part of the moving job. The force is 35 N to the left shown, and the box does not move. The coefficients of friction between the floor and box are µs = 0.75 and uk = 0.40. What is the minimum pushing force (magnitude only) needed to move the box, in Newtons? Useg = 10 m/s². Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
