- I was given this problem, and I don't really know what to do about the fact that the normal force doesn't equal the weight for this problem. How am I supposed to find the kinetic friction coefficient now? A box of mass 2,463g is on level ground being pulled by a force of 6.41N at angle 47.2 above horizontal. If the block is moving with a constant velocity, what is the kinetic friction coefficient? (Hint: the normal force does not always equal the weight; it does not in this case.)In the very Dutch sport of Fierljeppen, athletes run up to a long pole and then use it to vault across a canal as shown in (Figure 1). At the very top of his arc, a 70 kg vaulter is moving at 2.9 m/s and is 5.5 m from the bottom end of the pole. What is the magnitude of the vertical force that the pole exerts on the vaulter? Express your answer with the appropriate units.In the friction experiment, if the friction block has a mass of 599 g, and it started to move at a constant speed after giving it a slight push when the mass in the hanger is 284 g (including the hanger), what is the coefficient of kinetic friction?
- A skydiver weighing 65 kg jumps out of a helicopter hovering at a height of 3 kilometers. Assume a cross-sectional area of 0.5 square meters. After thirty seconds of free fall, the skydiver deploys the parachute and the cross-sectional area becomes 40 square meters. Reproduce the model for the skydiver in Excel or VenSim. In VenSim you may have to make At quite small in order not to throw an error. Because you reach terminal velocity relatively quickly your answer should not be particularly sensitive to the value of At you choose. What is the skydiver's terminal velocity without the parachute? meters/second What is the skydiver's terminal velocity with the parachute? meters/secondan object with mass m shown in the figure is attached to a spring with a spring constant k in a horizontal arrangement without friction, and the object is compressed as much as d. After the system is released, the object can rise to the height of h in the friction inclined plane. find the coefficient of kinetic friction between the oblique order and the body?A block of mass m rests on a plane inclined an angle with the horizontal. A spring with force constant k is attached to the block. The coefficient of static friction between the block and plane is s. The spring is pulled upward along the plane very slowly. (a) What is the extension of the spring the instant the block begins to move? (b) The block stops moving just as the extension of the contracting spring reaches zero. Express k (the kinetic coefficient of friction) in terms of s and .
