Airplane A is flying horizontally with a constant speed of 200 km/hr and is towing the glider B, which is gaining altitude. If the tow cable has a length r=60m and θ is increasing at the constant rate of 5 degrees per second, determine the magnitudes of velocity and acceleration of the glider for the instant when θ = 15 degrees. Relative motion What do we know? What are we trying to find? We are trying to find the velocity of B with respect to the ground.

Unformatted text preview: We know v A . What is it with respect to the airplane A? If we are trying to determine velocity of B wrt the ground, we should use x-y – how do we get et in terms of x-y? Solve for v B . Find a B . Doesn’t ask about forces, so is a kinematics problem. What relationship? Given: Find: v A = 200 km/hr, r AB = 60 m, θ _dot= 5 deg/s, θ = 15 degrees Velocity and acceleration of glider when Problem type:...
