Formative Exercise 8.2 Question 2
The diagram above shows a displacement-time graph of a particle moves along a straight line for t seconds. The equation of the curve PQ is s=ht2+k,where h and k are constants. The points P,Q,R and S are (0,1),(2,3),(4,3) and (6,0) respectively. Find
a) find the value of h and k
b) find the velocity of the particle, in ms-1,when i)t=1 ii)t=3 iii)t=5
