A blue car pulls away from a red stop-light

just after it has turned green with a constant

acceleration of 0.3 m/s². A green car arrives

at the position of the stop-light 7.5 s after the

light had turned green.

What is the slowest constant speed which

the green car can maintain and still catch up

to the blue car?

Answer in units of m/s.
