How do you work out deceleration!? Please answer quickly as I need to leave soon, thank you!
Acceleration =final velocity minus initial velocity over time

Therefore if it's decelerating then the initial velocity will be higher than your final velocity giving a negative velocity and then you'd divide it by time and your answer will be negative which is basically showing deceleration

Sorry if this doesn't make any sense

I think Hooke's Law is likely to come up.
Also they'll try and confuse us with velocity-time graphs and distance-time graphs and working out the distance
