Asked by Melissa
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?

acceleration = change in velocity/change in time
=4500 m/s / 30 s
= 150 m/s^2
or about 15 g
=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.
