Formative Exercise 8.2 Question 1
The diagram above shows a displacement function,s=f(t),velocity function,v=f(t) and acceleration function,a=f(t) for a particle which moves along a straight line and passes through a fixed point O for 0<t<4. Based on the graph,determine
a) the initial velocity of the particle,ms-1,
b) the time, in seconds, when the particle passes through the fixed point O,
c) the minimum distance, in m,of the particle,
d) the total distance travelled, in m,by the particle in the given time period,
e) the range of time,in seconds,when a particle moves to right.
