Aball is dropped off the top of a building that is 60 m high. the mass of the ball is 1.5 kg. when the ball hits the ground its ke is close to:

Looking at this barometer, is the air pressure high or low? what type of weather would you expect? high, bad low, bad high, good low, good

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) ! : )

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
