Maths AS level Mech questionWatch
Just wondering how the answer to part ii is true as it's accelerating from 10m/s to 20m/s in 28s but the answer is less than 280m. Please explain, using a graph if you can.
Why do you think the answer cannot be less than 280m? Do you feel that the acceleration must be greater than 10m/s??
u>=10 (as a >=0)
so S >=280
