1. In an acceleration test for a sports car, two markers 500 m apart were set up along a road. The
car passes the first marker with a velocity of 20 km/h [E] and the second marker with a velocity
of 120 km/h [E].
a) Calculate the car’s average acceleration between the markers in m/s2. [4]
b) How long does it take the car to pass the two markers, ie time interval between the two
markers? [2]
2. A stone is thrown straight up. To reach a maximum height of
8.0 m above its release point, what must its initial velocity be
in m/s? [4]
