    A cyclist is descending down a mountain with constant acceleration. She passes through three checkpoints, P, Q and R, with velocity 6 m s−1, x m s−1, and 20 m s−1 repsectively. The time to taken to travel from P to R is 35 s.
    A - Find the acceleration of the cyclist
    Given that t1/t2 = 4/3, where t1 is the time taken to travel from P to Q and t2 is the time taken to travel from Q to R.
    b - Find the value of x.
    c - Find the distance between P and R.

    For A, set up a SUVAT and solve for a.

    For B, find an expression for T(1):T(2). Then, set up two simultaneous SUVATs. Solve for x.

    For C, set up a SUVAT using all evidence you have so far, and solve for s.
