A paraglider has a total mass (which includes the equipment and body) of 95 kg when hovering on an air current.
1) What is the upward component of the force exerted by the air on the glider's wings?
2) If the air current exerts a force of 70 N to the West, what is the acceleration?
kindly
give rating

(13.1) An elevator riding in a frictionless vertical shaft has total mass of 1000 kg. (a) The elevator cable exerts a force of 9000 N in the upward direction on the elevator. Determine (i) the acceleration of the elevator, and (ii) how long it takes for the elevator, starting from rest, to attain a speed of 5 m/s. (b) The cable exerts a force of 12000 N [up] on the elevator. Determine (i) the acceleration of the elevator, and (ii)...
A boat has a mass of 5440 kg. Its engines generate a drive force of 4260 N due west, while the wind exerts a force of 940 N due east and the water exerts a resistive force of 1370 N due east. Take west to be the positive direction. What is the boat's acceleration, with correct sign?
A boat has a mass of 6802 kg. Its engines generate a drive force of 4078 N, due west, while the wind exerts a force of 841 N, due east, and the water exerts a resistive force of 1157 N due east. What is the magnitude of the boat's acceleration?
An elderly person with a body mass of 65 kg is walking while using a cane in one hand. If the upward force that the cane applies to the hand is 117 N and the vertical acceleration of the body center of mass is 1.32 m/s^2, what is the magnitude of the vertical ground reaction force? Assume that only one foot is on the ground and the other leg is in the swing phase
When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 964 N and the drag force has a magnitude of 1022 N. The mass of the sky diver is 98.4 kg. Take upward to be the positive direction. What is his acceleration, including sign?
A fully loaded, slow-moving freight elevator has a cab with a total mass of 1300 kg, which is required to travel upward 47 m in 3.5 min, starting and ending at rest. The elevator's counterweight has a mass of only 800 kg, so the elevator motor must help pull the cab upward. What average power is required of the force the motor exerts on the cab via the cable?
Suppose that you have a mass of 50 kg. When you pull the rip cord and the parachute opens, the air resistance force on you increases drastically and equals 2000 N upward. The magnitude of the acceleration is ______ m/s/s
You plan to fly a model airplane of mass 0.550 kg that is attached to a horizontal string. The plane will travel in a horizontal circle of radius 5.10 m. (Assume the weight of the plane is balanced by the upward "lift" force of the air on the wings of the plane.) The plane will make 1.10 revolutions every 3.50 s. (a) Find the speed at which you must fly the plane. (b) Find the force exerted on your hand...
A falling skydiver has a mass of 102 kg. What is the magnitude of the skydiver's acceleration when the upward force of air resistance has a magnitude that is equal to one-fourth of his weight?
A single mass (m1 = 4.3 kg) hangs from a spring in a motionless elevator. The spring constant is k = 266 N/m. 1) What is the distance the spring is stretched from its unstretched length? 2) Now, three masses (m1 = 4.3 kg, m2 = 12.9 kg and m3 = 8.6) hang from three identical springs in a motionless elevator. The springs all have the same spring constant given above. What is the magnitude of the force the bottom...
