Two figure skaters, one weighing 625 N and the other 725 N, push off against each other on very smooth ice. a)If the heavier skater travels at 1.50 m/s, how fast will the lighter one travel? b)How much kinetic energy is "created" during the skaters' maneuver?
A 0.2 kg softball is thrown straight up with an initial speed of 9 m/s. How high in meters does it go? Round to two significant figures.
A 1500 kg car is rolling horizontally at 2 m/s. You would like to stop the car by shooting a 10 kg blob of sticky clay at it, also horizontally. About how fast should you shoot the clay? O 25 m/s O2 m/s O 150 m/s 300 m/s O 0.01 m/s
Calculate the final speed (in m/s) of a 100 kg rugby player who is initially running at 7.50 m/s but collides head-on with a padded goalpost and experiences a backward force of 1.65 x 10* N for 7.50 x 10 -2 S. m/s
From 1946 through 1958, Col. John Stapp headed the U.S. Air Force Aero Medical Laboratory's studies of the human body's ability to tolerate high accelerations during plane crashes. Conventional wisdom at the time indicated that a plane's negative acceleration should not exceed 180 m/s2 (18 times gravitational acceleration, or 18g). Stapp and his colleagues built a 700-kg "Gee Whiz" rocket sled, track, and stopping pistons to measure human tolerance to high acceleration. Starting in June 1949, Stapp and other live subjects rode the sled. In one of Stapp's rides, the sled started at rest and 360 m later was traveling at speed 67 m/s when its braking system was applied, stopping the sled in 6.0 m. He had demonstrated that 18g was not a limit for human deceleration. Find the time interval for Stapp and his sled to stop as their speed decreased from 67 m/s to zero.
Flying Circus of Physics On August 10, 1972, a large meteorite skipped across the atmosphere above the western United States and western Canada, much like a stone skipped across water. The accompanying fireball was so bright that it could be seen in the daytime sky and was brighter than the usual meteorite trail. The meteorite's mass was about 3.7 × 106 kg; it's speed was about 14 km/s. Had it entered the atmosphere vertically, it would have hit Earth's surface with about the same speed. (a) Calculate the meteorite's loss of energy (as a positive number, in joules) that would have been associated with the vertical impact. (b) Express the energy as a multiple of the explosive energy of 1 megaton of TNT, which is 4.2 × 1015 J. (c) The energy associated with the atomic bomb explosion over Hiroshima was equivalent to 13 kilotons of TNT. To how many Hiroshima bombs would the meteorite impact have been equivalent? (a) Number (b) Number Units Units (c) Number Units
At the center of a 47.0 m diameter circular ice rink, a 56.0 kg skater traveling north at 2.60 m/s collides with and holds onto a 59.0 kg skater who had been heading west at 1.05 m/s. How long (in seconds) will it take them to reach the edge of the rink assuming negligible friction and drag?
tolerance is 3 sig figs
The superheroine Xanaxa, with a mass of 69.9 kg, is in a hair-raising chase after the 72.7-kg arch-villain Lexlax. She leaps from the ground to the top of a 195-m-high building, then dives off and comes to rest at the bottom of a 15.7-m-deep excavation, where she finds Lexlax and neutralizes him. Does all this bring about a net gain or a net loss of gravitational potential energy? Gain Loss By how much? Answer with a positive number. Take g = 9.81 m/s?. Number J
