Problem
On a displacement–time graph for one-dimensional motion, the slope of the tangent drawn at a particular instant represents
(a) the average velocity from the start to that instant
(b) the instantaneous velocity at that instant
(c) the instantaneous speed (magnitude of velocity) at that instant
(d) the average velocity between t and t+Δt
