Using SUVAT if s=(u+v)t/2
would t=2s/(u+v)?
would t=2s/(u+v)?

I would say I am reasonably ok with it. One question I am just doubting I am right with is this:
A car accelerates uniformly from 5ms-1 to 20ms-1 over a distance of 500m.
How long does this take (t)
What is the cars acceleration? (a)
obviously using s=(u+v)t/2 but I am unsure how to rearrange it correctly. Taking a guess at 2s/(u+v)=t which provides me with an answer of 10. I don't think its correct because using t to find A i end up with 15/10 which doesn't sound correct. Please help
SUVAT is a set of equations used in physics to describe the motion of an object in a straight line with constant acceleration. It stands for displacement (s), initial velocity (u), final velocity (v), acceleration (a), and time (t).
To solve for time using this equation, you need to rearrange it to isolate t on one side of the equation. This can be done by dividing both sides by (u+v) and then multiplying by 2, giving you t = 2s/(u+v).
Yes, this equation is specifically used for objects with constant acceleration. If the acceleration is not constant, the equation cannot accurately predict the time taken for an object to travel a specific distance.
No, SUVAT equations are only applicable for linear motion. For objects in circular motion, other equations such as those involving angular velocity and centripetal force should be used.
The units for displacement (s) are typically in meters (m), initial and final velocity (u and v) are in meters per second (m/s), acceleration (a) is in meters per second squared (m/s^2), and time (t) is in seconds (s).
