Which base units would be needed to express the SI unit of potential difference (the volt)? A m and A only. B s and A only. C m, s and A only. D kg, m, s and A. 2 A car travelling at a speed of 15.0 m s1 can be brought to rest in 1.20 s when a uniform braking force is applied. The reaction time of the driver is 0.100 s. What is the minimum distance at which the driver must notice a stationary object in order to avoid hitting it? A 1.50 m B 7.50 m C 9.00 m D 10.5 m 3 Which pair contains one vector and one scalar quantity? A displacement and acceleration B force and kinetic energy C momentum and velocity D power and speed 4 An object has an initial velocity u. It is subjected to a constant force that is not in the same direction as u, resulting in acceleration a. The vector diagram below is drawn to determine the object’s final velocity v after time t. What is the length of the vector X in the diagram? A v  u B v  u C at D u  at u X v
