The formula for kinetic energy is: K = 0.5 mv, where m is mass in kilograms, v is velocity in m/s, and K stands for the energy in Joules. If m = 30 kg, and v = 13 m/s, how fast is K changing if v is changing at the rate of 9 m/s? Assume m is constant. %3D Rate (in Joules/sec) = Number (Enter your answer rounded to 4 decimal places)

Can balloons hold more air or more water before bursting? A student purchased a large bag of 12-inch balloons. He randomly selected 10 balloons from the bag and then randomly assigned half of them to be filled with air until bursting and the other half to be filled with water until bursting. He used devices to measure the amount of air and water was dispensed until the balloons burst. Here are the data
An object is dropped straight down from a helicopter. The object falls faster and faster but its acceleration (rate of change of its velocity) decreases over time because of air resistance.
