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 the free-fall acceleration, 9.80 m/s^2.

The acceleration experienced by the astronauts would be 27908.37142 times the acceleration due to gravity on Earth

Explanation:

t = Time taken

u = Initial velocity = 0

v = Final velocity = 10.97 km/s = 10970 m/s

s = Displacement = 220 m

a = Acceleration

Equation of motion

The magnitude of acceleration is 273502.04 ft/s²

g = 9.80 m/s²

15 g = 15×9.80 = 147 N

So, the acceleration experienced by the astronauts would be 27908.37142 times the acceleration due to gravity on Earth

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts

what is the question because that is not a question.
