Achild and a shed with a combined weight of 50.0kg slide down a frictionless hill that is 7.3m high. if the sled starts from the rest, what is its speed at the bottom of the hill answer

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )

When solid surfaces slide over each other the kind of friction that occurs is called friction
