describe how to use a light gate to measure accelerationput double card on vehicle + record length of each let vehicle roll down ramp + through light gate record time taken for card 1 to pass through light gate. calculate and record initial speed. do same for card 2, final speed record time taken for both cards to pass through light gate use a=v-u/t
