Unformatted text preview: a) If the lower end of the chute is a vertical distance of h = 4.00 m above the ground, what has to be the velocity of the cart such that the package lands on the cart? (Hint: calculate first t*, the time it takes for the package to land. Express your answers in terms of t*). b) What is the speed of the package just before it lands in the cart? = 30 deg v0= 3 m/s D= 10 m H = 3 m 3) Two blocks are connected by a cord passing over a small frictionless pulley rest on frictionless planes at angles 1 = 30 degrees and 2 = 45 degrees respectively with the horizontal (see Figure). a) Draw free body diagrams for each of the block. b) If m 1 =10 kg, what has to be m 2 for the system to be in equilibrium? c) If I now reduce m 2 to be half of the equilibrium value, what is the acceleration of the system? m 1 m 2 45...
