4. Draw a sketch of a position-time graph, corresponding velocity-time graph, and corresponding acceleration-time graph (all on the same grid) so that the following are true: There are no points on the graph where v(t) = 0 ii. The slopes of the tangents to any point on the position-time graph is always negative iii. There is one point where a(t) = 0. *Your graphs can have restricted domains.1. What is the vector and parametric forms of the equation of the line passing through points P(-2.4) and 0(4, -4)
