Previous Answers SerCP10 2.P.028.WM My Notes Ask Your Teacher In 186s, Jules Verne proposed sending men to the Moon by firing a space capsule from a 220 m ong 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. m/s2 273502 827 AM /21/2017Explanation / Answer
Here, Initial Velocity, V0 = 11 cm/s
And, distance travelled by the object, x = -5.0 - 2.76 = - 7.76 cm.
Suppose the acceleration of the object = a cm/s^2
Now, use the formula -
x = V0*t + (1/2)*a*t^2
=> -7.76 = 11*3.55 + 0.5*a*3.55^2
=> - 46.81 = 6.30*a
=> a = - 7.43 cm/s^2
