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.

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
