Schematization Represents the initial and final states of the system, identifying an upward y+ axis for the block. Modelization Creates a model for the distance traveled by the block, based on known parameters only. Then test your model with the following values: Block mass: 18.1 kg Distance before rough part (D): 3.4 m Kinetic coefficient of friction: 0.24 Spring constant (k): 84 N/m Initial spring compression: 0.5 m

A block is given an initial speed of 4.8 m/s up the 23.0° plane shown in (Figure 1). Ignore friction. Figure m ▼ Part A How far up the plane will it go?

Part A A 55 g rock is placed in a slingshot and the rubber band is stretched. The magnitude of the force of the rubber band on the rock is shown by the graph in (Figure 1). The rubber band is stretched 30 cm and then released. What is the speed of the rock? Express your answer with the appropriate units.

Please answer question 8 parts a and d

Please use at least 4 significant figures throughout the entire problem! Also use 9.80m/s2 for the acceleration due to gravity. DO NOT USE 10 M/S2 FOR THE ACCELERATION DUE TO GRAVITY! Thank You.

A pile driver lifts a 250 kgkg weight and then lets it fall onto the end of a steel pipe that needs to be driven into the ground. A fall of 1.5 mm before striking the pipe drives the pipe in 40 cmcm.     Part A What is the average force that the weight exerts on the pipe? (Hint: Let the weight be the system)

Please solve and answer the question correctly. Thank you!

A 0.280 kg potato is tied to a string with length 1.50 m, and the other end of the string is tied to a rigid support. The potato is held straight out horizontally from the point of support, with the string pulled taut, and is then released. Express your answer in meters per second.

Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo spelled backwards). It is the very latest in home safety and so easy to use! If your building is on fire, simply reach out and grab the cord on the Oyoy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass M = 106.0 kg and is shaped like a cylinder of radius R = 0.835 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0830 meters. The cord is wound around the small shaft and this is the secret to your low velocity. Outer Radius = R Spindle Radius = r Mass = M The FORMULA for the moment of Inertia: I = V(y=0)=? We will use the approximation that the shaft is of negligible mass compared to the total. This means that you can treat the entire OyOy as though it is a solid cylinder with mass M and radius R. Imagine that a customer of mass m = 77.5 kg is using the Oyoy and…
