Question

Assume that an MX missile goes from rest to a suborbital velocity of 4.50 km/s in 90.0 s (the actual speed and time are classified). What is its average acceleration in m/s^2. What is its average acceleration in multiples of g?

Answer 1

Step-by-step explanation:

Given that,

Initial speed of the missile u = 0

Final speed of the missile, v = 4.5 km/s = 4500 m/s

Time taken by the missile, t = 90 s

Let a is the acceleration of the sports car. It can be calculated using first equation of motion as :

`v=u+at`

`v=at`

`a=(v)/(t)`

`a=(4500\ m/s)/(90\ s)`

`a=50\ m/s^2`

Value of g,
`g=9.8\ m/s^2`

`a=(50)/(9.8)\ m/s^2`

`a=(5.10)\ g\ m/s^2`

So, the acceleration of the missile is
`(5.10)\ g\ m/s^2`. Hence, this is required solution.
