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?

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 :

Value of g,

So, the acceleration of the missile is . Hence, this is required solution.

If the starting height of a sloped racetrack is increased, then the speed at which a toy car travels along the track will increase because the toy car will have a greater acceleration.
