Assume that an MX missile goes from rest to a suborbital velocity of 4.50 km/s in 30.0 s (the actual speed and time are classified). What is its average acceleration in m/s2?


What is its average acceleration in multiples of g?

3 answers

acceleration = change in velocity/change in time
=4500 m/s / 30 s

= 150 m/s^2

or about 15 g
can you tell me how you got that? I have a test soon and I seriously don't get it
I used the definition of acceleration

acceleration is how much your velocity changes per second.
so here it is the change in speed which is zero to 4500 m/s (1000 times the 4.5 because that was kilometers)
in 30 seconds.
