C is probably the correct one
Answer:
probably the trip where it took u 5 seconds
Answer:
The ball has kinetic energy
the kinetic energy is 945 J
Explanation:
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
