Answer:
The total momentum is
Explanation:
The diagram illustration this system is shown on the first uploaded image (From physics animation)
From the question we are told that
The mass of the first object is
The speed of the first mass is
The mass of the second object is
The speed of the second object is assumed to be
The total momentum of the system is the combined momentum of both object which is mathematically represented as
substituting values
Ok so we know:
The time (t) is 18seconds
The acceleration (a) is 2.2m/s2
The displacement (r) is 660
Using the equation
With 'u' being the initial velocity we want, we get:
So:
So:
So the original/initial velocity was 16.8666 or 16.87 m/s
Hope this helped
