SECTION B: MECHANICS

A cyclist travels along a straight horizontal road with constant acceleration. She passes point $A$ with speed $8$ m s⁻¹ and, $100$ m further along the road, passes point $B$ with speed $18$ m s⁻¹.
(a) Find the acceleration of the cyclist. (3 marks)
(b) Find the time taken to travel from $A$ to $B$ . (2 marks)
(c) State one assumption of the model used in your calculations. (1 mark)

A delivery van is waiting at traffic lights on a straight horizontal road. When the lights change, the van moves off from rest with constant acceleration $1.6\ \text{m s}^{-2}$

Find
(a) the speed of the van $7$ s after it moves off,

(1 mark)
(b) the distance travelled by the van during these $7$ s.
