Asmall car with mass 0.800 kg travels at constant speed on the inside of a track that is a vertical circle with radius 5.00 m. if the normal force exerted by the track on the car when it is at the top of the track (point b. is 6.00 n, what is the normal force on the car when it is at the bottom of the track (point a)?

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

An object weighs 40n in air, weighs 20n when submerged in water and 30n when submerged in a liquid of unknown density. what is the density of the liquid?

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) ! : )
