Question details

4. A radar station is tracking a plane flying at a constant altitude of h-10 km with a constant speed V. At the moment shown in the picture, if the radar angle θ 0.02 rad/s. Find and v. (3pts) 60° and is decreasing at a rate of 5. Motion of the sliding block P in the rotating radial slot is controlled by the power screw as shown. For the instant represented, d-8 rads, θ--20 rads, r-200 mm. Also, the screw turns at a constant speed giving r -300mm/s . For this instant, determine the r-and θ. components of the acceleration of P. (3pts) 6. A cart is moving horizontally with a constant acceleration. Inside the cart there is a steel ball suspended by the two cords A and B. If the tension in A is twice as that in B, what is the acceleration of the cart? (3pts) 60° 60
