View Policies Current Attempt in Progress A 4.0 kg lunchbox is sent sliding over a frictionless surface, in the positive direction of an x axis along the surface. Beginning at time t=0, a steady wind pushes on the lunchbox in the negative direction of the x axis. The figure shows the position x of the lunchbox as al function of time t as the wind pushes on the lunchbox. From the graph, estimate the kinetic energy of the lunchbox at (a) t = 1.0 s and (b) t= 5.0 s. (c) How much work does the force from the wind do on the lunchbox from t = 1.0 s to t= 5.0 s?

2.) A 1000 kg boat is towed in the water by a cable in a straight line. The Tension in the cable is 3,000N. The coefficient of friction between the boat and the water is µ = 0.2. It starts from rest and reaches a final speed of 5m/s after some unknown distance. Angles must be shown in your work calculations. a.) What is the final kinetic energy of the boat? b.) Using the Work-Kinetic Energy Theorem, find the unknown distance.

Taylore has a couch that she wants to move in Davidson Student Center's lounge, with mass 12.7 kg. The couch starts at rest. Taylore pushes with an 24.4 N force, and the object has a displacement of 11.2 m, directed 30.0° from the direction of the force. What is the final speed of the couch? Your Answer: Answer
You are working out on a rowing machine. Each time you pull the rowing bar (which simulates the oars) toward you, it moves a distance of 1.20 m in a time of 1.80 s. The readout on the display indicates that the average power you are producing is 102 W. What is the magnitude of the force that you exert on the handle? i 3
Common speech often uses the term "work" to refer to situations where, according to the physics definition of work, there is no actual work done. Find an example of this and explain why the non-physics public considers this work and what a proper physics response would be to this error. You must use ordinary language in an attempt to clarify what is happening do not rely on trigonometry or scalar dot products in you answer . Some examples you could consider include a person pushing on a wall and the wall not moving, a person doing a "bench seatisometric exercise where they squat against a wall, the moon being pulled by gravity as it orbits the earth, etc.
A child stands on a bank beside a pond, grasps the end of a 20.0 m long rope attached to a nearby tree and swings out to drop into the water. When the rope makes an angle of 15.0⁰ with the vertical, the child's speed is 5.00 m/s. a) At what point in the swing does the child's maximum speed occur? b) What is the child's maximum speed? Ignore all frictional effects. c) Assuming the child started from rest, what angle did the rope initially make with respect to the vertical?
PRINTER VERSION 4 ВАСК NEXT Chapter 08, Problem 069 Z Your answer is partially correct. Try again. In the figure the pulley has negligible mass, and both it and the inclined plane are frictionless. Block A has a mass of 1.0 kg, block B has a mass of 2.2 kg, and angle 0 is 27 °. If the blocks are released from rest with the connecting cord taut, what is their total kinetic energy when block B has fallen 21 cm?
