QA3- RELATIVE MOTION A helicopter is flying North-West at 80 m/s relative to the ground and the wind velocity is 15 m/s from the East. The helicopter's main rotor lies in a horizontal plane, has a radius of 6 m, and is rotating at 20 rad/s in a clockwise sense looking down on it. a) Calculate the helicopter's air speed and apparent heading through the air (i.e. both relative to the air). b) Calculate the maximum and minimum velocities of the blade-tips relative to the air. Hint: In both parts, draw sketches to visualise what's happening. In the second part, only consider the helicopter's motion through the air and the blade-tips' motion relative to the helicopter (i.e. the air becomes your main reference frame, not the ground).

A rope of length L = 2.4 m and mass m = 3.9 kg is initially at rest and can slide on an inclined surface with incline 0 = 25° as shown in the figure. Assume that the part of the rope that is not on the inclined surface hangs down vertically at all times and that the static friction coefficient between the rope and the surface is μ = 0.54. 0/
The rotation axis of the uniform cylinder is constrained by a frictionless slot. The cylinder is at rest when it is lowered onto the conveyor belt, which has a constant translational velocity of 20.0 ft/s. The coefficient of friction between the belt and the cylinder is 0.400.a) Calculate the maximum angular velocity of the cylinder.b) The distance traveled by the belt during the time the cylinder is accelerating to its maximum angular velocity
Dynamics 1-There is a spring with the initial length of 0.4 m and its constant is 200 N/m. The slider attached to this spring which is at position A.

If the system is on the vertical plane and there is no friction: A) Find the reaction force from the rod on the slider at position C B) What is tangential acceleration of the slider at position C? C) Determine the velocity of the slider at position B. 40° 0.8 m B. 0.6 m www
This question is similar to the question above but read and calculate carefully. The situation has changed and the numbers have changed. Bonita Cart Bonita is again pulling a cart to the right. The cart used to be tied to a wall but now the rope has broken so the cart rolls over the horizontal floor without friction. Assume that the only forces on the cart are tension forces (including the force from Bonita), normal forces, and gravity with g = 9.81 m/s?. Bonita's shoes do not slide over the floor. Bonita has a mass of 52 kg. The cart has a mass of 45 kg. The mass of the rope is small enough to be ignored. Bonita is pulling the cart with a constant force of 283 newtons. Calculate the magnitude of the force that the cart exerts on Bonita. Note that the magnitude of a force is a positive quantity.
a.) What is the angle, measured relative to the positive x-axis, of the load's acceleration? (The correct answer is: -10.219 degrees) Just need the steps to get there b.) Three horses pull and guide a 132 kg payload down a river, exerting the forces shown in the figure, with F1 = 29 N, F2 = 38 N, F3 = 58 N, θ1 = 30°, and θ2 = 60°. What is the magnitude of the payload's acceleration? (The correct answer is: 0.7861 m/s^2)Just need the correct steps to get there
