A space shuttle is launched from rest. It takes 8.00s to reach 157km/h , and at the end of the first 1.00 min its speed is 1570 km/h . Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the shuttle travel during the first 8.00s ? Assuming the acceleration is constant during each time interval (but not necessarily the same in both intervals), what distance does the shuttle travel during the interval from 8.00s to 1.00min ?
The wave is travelling to the right at 50.0 m/s. What is the amplitude if the highest displacement is 38.0 cm and the total distance travelled by the wave is 16.0 m.
A freight train has a mass of 2 multiplied by 107-kg. If the locomotive can exert a constant pull of 12.50 multiplied by 105-N, how long would it take to enhancement the speed of the train from rest to 85.00 km/h.
Write down an expression for the efficiency of the air cart bumper in terms of the initial and final kinetic energy of the cart. What defines a collision as elastic or inelastic.
Two adjacent sources each emit a frequency of 800Hz in air where the velocity of sound is 340 m/s. How much farther back would source 1 have to be moved as a result an observer in front of the sources would hear no sound.
Kelli weighs 405 N, and she is sitting on the playground swing that hangs 0.43 m above the ground. Her mom pulls the swing back and releases it when the seat is 1.00 m above the ground. suppose that air resistance is negligible.
