A cannon shoots a cannonball from ground level at an angle of 60 degrees from the ground with a total velocity of 25 m/s. solve for the time it takes for the ball to hit the ground.

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

If the textbook weighs 19.6 newtons on venus,what is the strength of gravity on venus?

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) ! : )
