What is the magnitude of the sky diver's acceleration at the instant the parachute opens? Express...
When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 964 N and the drag force has a magnitude of 1022 N. The mass of the sky diver is 98.4 kg. Take upward to be the positive direction. What is his acceleration, including sign?

Rod O A rotates counterclockwise with a constant angular velocity of θ=5 rad / s. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r=1.5(2-cosθ) ft. (Figure 1)Part AIf both collars weigh 0.80 lb, determine the magnitude of the normal force which the curved rod exerts on one collar at the instant θ=110° . Neglect...

Problem 3.24 What is the magnitude of the force he must exert on the rope in case a? Figure 1) Express your answer with the appropriate units. Constants The person wants to cause the 240 lb crate to start sliding toward the right. To achieve this, the horizontal component of the force exerted on the crate times the normal force exerted on the crate by the floor. In Fig. a, the person pulls on the rope in the direction shown....
