Concept - here friction is absent on the slope. Hence, energy will be conserved. We apply work energy theorem where the work done by the gravity causes an increase in kinetic energy of the ski as it reaches near bottom.

X Question ellawyn rides a sled from the top of a snowy hill ti the bottom. she starts ar a height of 9 m and rides down the frictionless hill. the ground at the bottom of the hill is horizontal and rough, the coefficient of kinetic friction between the sled and the ground is.05 and the coefficient of static friction is.1. how far does the sled slide along the rough horizontal ground at the bottom of the hill until it...
Conservation of energy A child on a sled slides from rest from the top of a 20.0 m high very slippery hill. The total mass of the child and the sled is 30.0 kg. Treat the bottom of the hill as a reference. a. b. c. d. e. What is the kinetic energy of the child and sled at the top? What is the potential energy at the top? What is the potential energy at the bottom? What is the...
a child of mass 25 kg sits at rest at the top of a frictionless slide 2.0m off the ground. He then slides down. what is his kinetic energy at the bottom of the slide?
Nicola ans Sofia are ski racing on a 15 degree slope. The race consist of going in a straightfine until the end of the slope. Their respective masses are 75 Kg and 53 Kg. Considering there is a coefficient of kinetic ifction of 0.12, which of these affirmation is true? Select one: In theory, they should arrive at the same time as the bottom of the hill. Nicolas will arrive first at the bottom of the hill since his mass...
