You are a member of an alpine rescue team and must get a box of supplies, with mass 2.10 kg , up an incline of constant slope angle 30.0 ∘ so that it reaches a stranded skier who is a vertical distance 2.80 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10−2. Since you can't walk up the incline, you give the box a push that gives it an initial...
You are a member of an alpine rescue team and must get a box of supplies, with mass 2.60 kg , up an incline of constant slope angle 30.0 ∘ so that it reaches a stranded skier who is a vertical distance 3.30 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10−2. Since you can't walk up the incline, you give the box a push that gives it an initial...
Need the exercise portion Hit the Ski Slopes EXAMPLE 5.8 GOAL Combine conservation of mechanical energy with the work-energy theorem involving friction on a horizontal surface. h = 20.0 m у A skier starts PROBLEM from rest at the top of a frictionless incline of height (В С) 20.0 m, as in the figure. At the bottom of the incline, the skier The skier slides down the slope and onto a level surface, stopping after encounters a horizontal traveling a...
Use the work–energy theorem to solve each of these problems. You can use Newton’s laws to check your answers. A)A skier moving at 4.25 m/s encounters a long, rough, horizontal patch of snow having a coefficient of kinetic friction of 0.220 with her skis. How far does she travel on this patch before stopping? B)Suppose the rough patch in part A was only 2.89 m long. How fast would the skier be moving when she reached the end of the...
Use the work–energy theorem to solve each of these problems. You can use Newton’s laws to check your answers. A) A skier moving at 5.57 m/s encounters a long, rough, horizontal patch of snow having a coefficient of kinetic friction of 0.220 with her skis. How far does she travel on this patch before stopping? Express your answer with the appropriate units. B) Suppose the rough patch in part A was only 2.99 m long. How fast would the skier...
Part A With what minimum speed must you toss a 200 g ball straight up to hit the 15-m-high roof of the gymnasium if you release the ball 1.5 m above the ground? Solve this problem using energy. Express your answer using two significant figures. (answer v_min = m/s) Part B With what speed does the ball hit the ground? Express your answer using two significant figures. (answer v = m/s)
