A 18 kg child slides down a 4.0 m-high playground slide. She starts from rest, and her speed at the bottom is 2.8 m/s. What is the change in the thermal energy of the slide and the seat of her pants?
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 33 kg child slides down a playground slide at a constant speed. The slide has a height of 4.0 m and is 8.0 m long. Part A Using the law of conservation of energy, find the magnitude of the kinetic friction force acting on the child.
A 27 kg child slides down a playground slide at a constant speed. The slide has a height of 3.8 m and is 7.4 m long. Using the law of conservation of energy, find the magnitude of the kinetic friction force acting on the child.
A child goes down a playground slide with an acceleration of 1.34 m/s2 . Find the coefficient of kinetic friction between the child and the slide if the slide is inclined at an angle of 35.0 ∘ below the horizontal.
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?
A child goes down a playground slide with an acceleration of 1.28 m/s2 . You may want to review (Pages 156 - 163) . Find the coefficient of kinetic friction between the child and the slide if the slide is inclined at an angle of 32.0 ∘ below the horizontal.
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)
A 45 kg child slides down a straight frictionless water slide. The slide is 16 m long and set at angle of 28o above horizontal.1.Find the work done by gravity on the child.2.If the child started at rest at the top, what is the speed of the child at the bottom of the slide?
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
