Question 2

From Physics HL Paper 1A (May 2025, TZ1)

  1. The variation with time tt of the acceleration aa of an object is shown. At t=0t = 0 the object is at rest.
Graph showing acceleration (a) in ms^-2 versus time (t) in s. The graph is a straight line passing through the origin and (10, 10).
Graph showing acceleration (a) in ms^-2 versus time (t) in s. The graph is a straight line passing through the origin and (10, 10).

What is the speed of the object when t=8.0 st = 8.0\text{ s}?
