A 15.0 kg child descends a slide 2.8m high and reaches the bottom with a speed of 2.3 m/s. How much thermal energy due to friction is generated in this process?
10.you are asked to design a friction-less playground slide such that the speed a child reaches at the bottom does not exceed 19 m/s. determine the maximum height (in meters) that the slide can be.
A child leaves her book bag on a slide. The bag, which is at the top of the slide, starts from rest and reaches the bottom in 1.73 s. The mass of the book bag is 3, 30 kg, the length of the slide is 3.70 m and the angle of incline is 31.oe. (Assume the +x-axis to be parallel to and down the slide. For all values, enter the magnitude only.) With what acceleration does the bag go down...
30-kg child slides down a playground slide as shown below. At the bottom of the slide, the speed of the child is 1.0 m/s. How many joules of internal energy were gained by the child and slide along the way? 2.5 m 30°
A 29.00-kg child initially at rest slides down a playground slide from a height of 3.10 m above the bottom of the slide. If her speed at the bottom is 2.40 m/s, how much energy is lost due to friction?
9. A child of mas 40kg runs at a speed of 5 m/s and jumps onto a disc shaped merry go round of mass 100 kg and radius 5m. The child lands on the outer edge of the disc when the disc is stationary.. What is the angular speed of the merry go round with the child on it? Was energy lost? If so, how much energy was lost in the process? loo kg 5 he
A child slides down a slide with a 20 degree incline, and at the bottom her speed is percisely half what it would have been if the slide was frictionless. Derive an equation for the acceleration with friction and for acceleration without friction. Calculate the coefficient of friction between the slide and the child. Bonus: (5pts) Must have everything correct A child slides down a slide with a 20 incline, and at the bottom her speed is precisely half what...
A child whose weight is 270 N slidesdown a 6.2 m playground slide that makesan angle of 20° with the horizontal. The coefficient of kineticfriction is 0.10. (a) How much energy is transferred to thethermal energy? 1 J (b) If she starts at the top with a speed of 4.97 m/s, what is herspeed at the bottom? 2 m/s
A child whose weight is 267 N slides down a 6.10 m long slide that makes an angle of 20.0° with the horizontal. The coefficient of kinetic friction between the slide and the child is 0.100. If the child starts at the top with a speed of 0.457 m/s, what is the child's speed at the bottom? (Ignore air resistance)
Starting from rest, a 29.2 kg child rides frictionless ski slope. At the bottom of the hill, her speed is 8.25 kg sled down a a 6.8 m/s. If the slope makes an angle of 15.5° with respect to the horizontal, how far along the hill did she slide on C her sled? 0.235 distance Momentum and Energy 2 Based on the previous question you can conclude that if two objects of different mass have the same magnitude of momentum,...
