An eagle flying at 20 m/s at 30° along an arc (radius of curvature p= 50 m) accidentally drops its prey at t=0. When the prey drops 5 m in altitude, it is tracked by the boy's iPhone Al camera. The boy is riding a cart on a 20° deg slope, and the cart is being pulled by a truck using the pulley-and-cable arrangement shown. If at the instant the camera detects r=100 m, r = -24 m/s, -12 m/s², and =30° (measured from the slope), determine the velocity and the acceleration of the truck. Ans: VA=12.517 m/s, a₁ = 1.999 m/s² Checkpoints: VB= 2.4072 m/s, 0=0.05425 rad/s, ag= 5.519 m/s² VB Ав 20° Y=100m +0=30° 12m e-som 5m arc JA, QA 5m A
