Assume that an mx missile goes from rest to a suborbital velocity of 4.50 km/s in 40.0 s (the actual speed and time are classified). what is its average acceleration in m/s2? 112.5 correct: your answer is correct. m/s2 what is its average acceleration in multiples of g?

Respuesta :

Indistinct
acceleration = change of speed / change in time = (v2 - v1) /( t2 - t1) = (4,5 km/s - 0 km/s) / 40 s = 0,1125 km /s^2 = 112,5 m/s^2
112,5 m/s^2 / earth's acceleration which is 9,8 m/s^2 = 11,5
So, this acceleration is 11,5 times bigger than earth's acceleration. The answer is 11,5g
