Use the worked example above to help you solve this problem. A skier starts from rest at the top of a frictionless incline of height 20.0 m, as shown in the figure. At the bottom of the incline, the skier encounters a horizontal surface where the coefficient of kinetic friction between skis and snow is 0.182. Neglect air resistance. (a) Find the skier's speed at the bottom. (b) How far does the skier travel on the horizontal surface before coming to rest?

Format of the output: GRESA (Given, Required, Equation, Solutions, Answer) 1. What is the net work of a system if there is an applied force pushing it at a value of (GIVEN A)N at a distance of (GIVEN B)m if there is a resisting force caused by the surface of a floor having a coefficient of kinetic friction value of (GIVEN C)? The mass of the object is (GIVEN D)kg. What is the final velocity of the object upon reaching the last point of the distance covered? Express work in proper scientific notation.

A box with weight of magnitude FG=2.00N is lowered by a rope down a smooth plane that is inclined at an angle ϕ = 30.0 ∘ above the horizontal, as shown in (Figure 1) at left. The normal force acting on the box has a magnitude n=1.73N the tension force is 1.00 N, and the displacement Δr of the box is 1.80 m down the inclined plane. The work done on the box by gravity is 1.8 J What is the work Wn done on the box by the normal force? What is the work WT done by the tension force?

In a downhill ski race, your final velocity is not affected very much by getting a running start, because the initial kinetic energy is compared with the gain in gravitational potential energy on even small hillsHowever, you will finish the race much faster (which is more important ) To demonstrate this, find the final speed and the time taken for a skier who skies 82.5 m along a slope that is 19 degrees measured from horizontal , in the following situations (you may neglect friction ) A find the final speed in m/s lf the skier starting from rest B how long (in s) does it take for the skier to reach the bottom of this hill starting from rest C find the final speed in (m/s) of the skier with speed of 2.50 m/s D how long in (s) does it take for the skier to reach the bottom of this hill with a starting speed of 2.50 m/s

Only parts A & B please.

Please just do part (d) for this question. Thank you

A miniature hill in a child’s toy collection is shown below. When released at A, a mass m slides down the path shown below, reaching the bottom (B) with a speed of vB. Assume that the hill has negligible friction. The block then slides along the rough horizontal surface a distance d before coming to rest at C.    When solving parts (a) and (b): Write the useful description about what is known and unknown. Write down the physics principle or strategy you will use. Symbolically solve for the unknowns   (a) Calculate the height of the hill using m=230.0 g and vB = 3.8 m/s (b) What is the coefficient of kinetic friction along the horizontal surface if d=14 m? Hint: Treat the motion down the hill and the motion down the rough horizontal surface as two distinct problems. What physics concepts can you apply for each?
