Hi

what is the idea for solving this question ?

What kinematic formula might be relevant?

 

[Infinitum]

The equations of motion under uniform acceleration. You'll get two equations in 'a' and 'initial velocity', from which you can solve for the other variables.

Ok

then we use this equation

S = ut + 1/2at^2

thanks
