s=uv + 0.5at^2
So what do you get? Assuming it's ut.

what do you mean? I get an overall quadratic equation of 4.9t^2+5-5

Check the "u" part in your suvat equation. Then you have a quadratic equation, so solve it.

Check the u part. Maybe pause/reflect a couple of minutes before replying?
Then you've missed the = 0 as it's an equation. Then solve.

I don't know what you are trying to say...what do you mean to check on in the initial velocity if it's already given

The quadratic expression does not match the suvat equation with u=5.

What is missing from the +5 term?
