- Physics help Q: starting from rest, a runner accelerates at a constant rate of 2 m/s^2 for a time of 6 seconds. Answer show work in detail and input values into the table attached belowI am still not sure how you got to the final result. I am still studying the work-energy theorem and on case 2 I don't understand how you simplified from the 1st formula line to the 2nd line. Can you please explain?On an essentially frictionless, horizontal ice rink, a skater moving at v = 3.0 m/s encounters a rough patch that reduces her speed to 45% due to a friction force that is 25% of her weight (w). Use the work-energy theorem to find the length of this rough path.Express first your answer in terms of any or all of the variables v, w, and g (acceleration due togravity), and then its numerical value
- A child of mass m = 16 kg slides down a slide of height h = 2.7 m without friction. Let gravitational potential energy be zero at ground level. a)Write an expression for the child's total mechanical energy, E, at the top of the slide, in terms of the variables in the problem and the acceleration due to gravity g. b)Calculate the change in the child's potential energy, ΔU in joules, from the top to the bottom of the slide at ground level (i.e. ΔU = Uground - Utop). c)What is the child's final speed, vf in m/s?Consider the following physical situations. Identify the forces which do work upon the indicated object (in boldface type) and categorize them as conservative or non-conservative forces. Then indicate whether the total mechanical energy of the object changes; it it changes, then indicate whether the change is a positive or negative change. Finally, indicate whether the potential energy and the kinetic energy changes; if PE or KE changes, then indicate whether the change is a positive or negative change.

A force is applied to move a physics cart from the floor to the top of an inclined plane at a constant speed. _________ _________ _____ _____ _____ _____ _____ _____ b. A physics student scurries up a flight of stairs at constant speed. _________ _________ _____ _____ _____ _____ _____…A block of mass 7.50 kg is being pulled along a level surface as shown, by a force directed at 30.0 degrees above horizontal. The pulling force has a magnitude of 68.0 N. Ignore the friction for now. If the total work done by the pulling force is 255 J, then how far has the block traveled? Hints on solving strategy: Remember from Flipping Physics that work is measured in Joules (J). You'll need to use the formula Mr. P gives for calculating the work done by a force over a given displacement.
- Question 1 The first question does not require the coefficient of friction. Doesn't all the work being performed by the system = friction? Friction is the only thing that is performing work?How do you know if the work done by a force acting on an object is positive or negative? Hint: Work is a scalar but both force and displacement are vectors.How did you solve D? Wouldn't it's distance be different from that of Point 1 to Point 2 as would be Point 3 to Point 2 and shouldn't that effect the answer for work needed to be done?
