M1 stuff. I just need to see how the formulae could be applied for these, I can't see it. More than likely, once again, I've missed something obvious.

6. A particle moves along a line PQ with constant acceleration 3ms-2. If PQ is 2m and the particle takes 0.5s to travel from P to Q, what was it's velocity at P?

7. A particle travels in a straight line with uniform acceleration 8ms-2. If it's initial velocity is 2ms-1, how long will it take to travel 6m?

You've got a, s and t and you're trying to find u so use .6. A particle moves along a line PQ with constant acceleration 3ms-2. If PQ is 2m and the particle takes 0.5s to travel from P to Q, what was it's velocity at P?

You've got a, u and s and you're trying to find t so use the same equation.7. A particle travels in a straight line with uniform acceleration 8ms-2. If it's initial velocity is 2ms-1, how long will it take to travel 6m?

Bash it with a hammer.

You've got a, s and t and you're trying to find u so use . You've got a, u and s and you're trying to find t so use the same equation.

Just rearrange the formula then? Fair enough.

Once again, I knew it was something obvious at the back of my mind
