The vertical component of the acceleration of a sailplane is zero when the air pushes its wings with a lift force of 3.30 kN. Assume that the only forces on the sailplane are that due to gravity and that due to the air pushing up against its wings.
A. What will be the gravitational force on Earth due to the sailplane?
B. If the wing stalls and the upward force decreases to 1.51 kN, what is the acceleration of the sailplane?

An aircraft with swept wings is flying at zero bank angle. A sudden disturbance in the air causes it to roll towards the left. What will happen to the lift force on the left wing? It will decrease as the effective angle of attack on the left wing increases. It will decrease as the effective angle of attack on the left wing decreases. It will increase as the effective angle of attack on the left wing decreases. It will increase...

1. A Ferris wheel has a radius of 6 m and makes one revolution in 4seconds (i.e. onerevolution in approximately 12.6 seconds). A person with a mass of 50 kg is sitting on one of thebenches attached to the rim. What is the normal force acting on a the person at the highest pointof the rotating Ferris wheel? Approximate the acceleration due to gravity as 10 m/s2; on a Ferriswheel, the passengers are never upside down. 2. Consider what happens...

QUIZE LAB 8 GRAVITY AND AIR RESISTANCE a. Select the true statement(s): (2 points) In vacuum, all objects, no matter the mass, should theoretically fall with the same acceleration The weight of an object on Earth is same as the weight it would have on the moon. The weight would vary slightly at different locations on the earth's surface becauseg varies slightly from place to place on the earth. * * . The gravitational acceleration g 4.9 N/k 2. Select...
The following objects all have a net force of zero Newtons and are therefore in equilibrium. In each case some forces acting on the object are provided. Discuss the total number of forces acting on the object and add the missing forces. You may elect to choose from the provided list of forces, but feel free to discuss/provide a force that is not listed, if you feel your explanation is better. List of possible forces: Weight (The pull of gravity)...
Q1) Answer all Multiple Choice questions.i) Newton’s 1st law is:A. PHYSICALLY INDEPENDENT of the other two laws
of motion and CANNOT be dispensed with as an axiom
of Newtonian physics.B. PHYSICALLY INDEPENDENT of the other two laws
of motion, but nonetheless it CAN be dispensed
with as an axiom of Newtonian physics.C. Actually a SPECIAL CASE of the 2ND LAW. The
case when the net force is zero. Therefore, logically we need only
two laws of motion. Perhaps for clarity...

Use the worked example above to help you solve this problem. An
airplane has wings, each with area 4.05 m2, designed so
that air flows over the top of the wing at 249 m/s and underneath
the wing at 226 m/s. Find the mass of the airplane such that the
lift on the plane will support its weight, assuming the force from
the pressure difference across the wings is directed straight
upwards.
Your response differs from the correct...
On an airplane's takeoff, the combined action of the air around the engines and wings of an airplane exerts a 3080-N force on the plane, directed upward at an angle of 57.0" above the horizontal. The plane rises with constant velocity in the vertical direction while continuing to accelerate in the horizontal direction (a) What is the weight of the plane? N (b) What is its horizontal acceleration? Buon Antwer
