Suppose sonic accelerates, running 55 meters in 5 seconds. Now how fast is he moving?

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

Anybody wanna ? (picture included? )

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) ! : )
