Kinetic energy varies jointly as the mass and the square of the velocity. a mass of 15 grams and velocity of 3 centimeters per second has a kinetic energy of 27 ergs. find the kinetic energy for a mass of 5 grams and velocity of 9 centimeters per second.

Assume similar data for the motion of the blood in your aorta. estimate how many beats of the heart it will take the blood to get from your heart to your brain. (assume that the distance from your heart to your brain is 30 cm)

What occurs during a combustion reaction

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
