Tony shoves 3 objects off the railing of a 2nd-story balcony at the same time, and at the same initial velocity. the three objects are a rock, a tennis ball, and a golf ball. the 2nd story balcony railing is 12.0 feet above the ground, and all three objects hit the ground just 0.350 feet away from the base of the building at the same time, 0.863 seconds after they\'re dropped. the rock hits the dirt with a smack and stays put, but the other two objects bounce. after another 0.647 seconds, the tennis ball reaches a maximum height of 6.75 feet, while the golf ball is 9.45 feet off the ground and still rising. both have travelled an additional 0.263 feet horizontally (their horizontal velocity components are equal). determine the magnitude of the average velocity for each body during the full 1.51 seconds. which object\'s instantaneous velocity has the largest magnitude at the end of this time period?

Estimate the schwarzschild radius (in kilometers) for a mini-black hole formed when a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (assume that the your weight is 50 kg)

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
