In 1865, Jules Verne proposed sending men to the Moon by firing a space capsule from a 220-m-long cannon with final speed of 10.97 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during their launch? (A human can stand an acceleration of 15g for a short time.) Compare your answer with thr free-fall acceleration, 9.80 m/s^2
The minimum stopping distance for a car traveling at a speed of 30 m/sm/s is 60 m, including the distance traveled during the driver's reaction time of 0.50 ss . What is the minimum stopping distance for the same car traveling at a speed of 47 m/sm/s ? Express your answer to two significant figures and include the appropriate units.

A ball is thrown into the air by a baby alien on a planet in thesystem of Alpha Centauri with a velocity of 49 ft/s. Its heightin feet after t seconds is given by y = 49t −25t2.a.) Find the average velocity for the time period beginningwhen t0 = 1 second and lasting for the given time.t = .01 sec:t = .005 sec:t = .002 sec :t = .001 sec: b.) Estimate the instanteneous velocity when t = 1.
Jane is driving down the road at 20.0 m/s looking for a house address. when she sees the house, she slams on her brakes. If her reaction time is 1.20s and her car deaccelerates at 3.50 m/s^2, how far past the point where she first saw the house did her car come to rest? I feel like I need to use one of the 4 kinematics equations, but none seem to be giving me the correct answer when I plug in my numbers :(
Usain Bolt wants to complete a10kilometer-run in less than30 minutes.After running at constant speed for exactly26 minutes, the runner still has1.5kmleft to run.The runner must then accelerate at0.30m/s2for how many seconds to reach a final velocity that will allow them to complete the1.5kmleft of the race in the desired time?
A rocket ship has a position given by x(t)=bt2 meters. In order for it to reach a velocity of 5,000 m/s in 40,000 meters, what must be the value of b?
In April 1974, Steve Prefontaine completed a 10.0 km race in a time of 27 min, 43.6 s. Suppose "Pre" was at the 8.41 km mark at a time of 25.0 min. If he accelerated for 60 s and then maintained his increased speed for the remainder of the race, calculate his acceleration over the 60 s interval. Assume his instantaneous speed at the 8.41 km8.41 km mark was the same as his overall average speed up to that time. acceleration: ?
Bacteria move back and f01th by using their flagella (Structures that look like little tails). Speeds of up to 50m/s(50106m/s) have been observed. The total distance traveled by a bacterium is large for its size, while its displacement is small. Why is this?
Two very hungry (and competitive) pre-med students suddenly see a parked ice cream truck that is that is down to its last ice cream cone. The truck is a distance of D meters away from the nearest student, who runs toward the truck at 2.5 m/s, and the second student (who was a track star in high school) runs toward it faster at 5.7 m/s but the second student is 10.0 meters farther away (to where he has to run D+10.0 m). What is the maximum possible value of D for the two students to reach the ice cream truck at the same time?
If a running back gets hit while he is moving at 2.24 m/s and experiences an accleration -12.8 m/s2, how long will it take him to stop running?
I had a dream last night that I was chased by my teddy bear. In my dream, I was sleepwalking at a constant velocity of 60ft/sec. At exactly 4:00 am I noticed my teddy bear standing 1000 feet behind me. At that instant I began to accelerate at 10 ft/sec/sec and the teddy bear began to accerlate after me at 12 ft/sec/sec. At the moment the bear caught up to me, I woke from my dream in a cold sweat. To the nearest second, What time was this?
