Cars A and B are travelling in the same direction along a straight road. The time t is in seconds.
At t = 0, car A is at rest. It accelerates at 3 ms-2 for 0⩽t⩽10
and then travels at a constant speed.
Car B travels at 15 ms-1 for
0⩽t⩽30 and then accelerates at 1 ms-2 until it reaches a
speed of 25 ms-1, after which it continues at this constant speed.
(i) Draw v-t diagrams for the motion of car A and of car B, where v is the speed in ms-1 and 0⩽t⩽80
(ii) Show that, in the first 40 seconds, car A travels 400 m further than car B.
(iii) Given that car A is 500 m behind car B at t = 0, at what value of t does car A catch up with car B?
If anyone's willing to take the time to help me with this question, I'd be super grateful. I'm really stuck on this right now.

Question part points submissions used suppose that 100 lottery tickets are given out in sequence to the first 100 guests to arrive at a party. of these 100 tickets, only 12 are winning tickets. the generalized pigeonhole principle guarantees that there must be a streak of at least l losing tickets in a row. find l.
