Hi

I'm just revising forces and am up to deceleration

It's all pretty comprehendable, i just wondered when you're at college are you allowed to use a calculators or is it like school where you get calculator and non-calculator tests? I ask because although i understand how to do the equations i get stuck when i have to do sums with point numbers (i.e. 12 x .87) also in terms of deceleration you have to divide by minus numbers

Now this is easy when you've go: "A truck decelerates from 25m/s to 5m/s in 5s" But if the truck decelerated from 28.5m/s to 4.8m/s in 5.2s then i would deffinately need a calculator. Or is it a case of rounding the numbers? (I imagine you have to bee pretty precise though.)

Thanks

Ben
