A resultant force of 20N gives a body of mass m1m1  an acceleration of 8 m/s28 m/s2  and a body of mass m2m2  an acceleration of24 m/s224 m/s2 . What acceleration will this force cause when two masses combine together

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) ! : )
