D) Rearrange and solve practical problems involving linear and quadratic equations.

The distance s metres travelled in time t seconds is given by the formula:

where u is the initial velocity in m/s and a is the acceleration in m/s²

s = ut + + at ²

i) Rearrange this equation in terms of the acceleration, a

ii) Find the acceleration of the body if it travels 168m in 6s, with an initial velocity of 10 m/s
