Hi thank you for the tutorial! But may I clarify when you tried to subtract velocity of speeder to police car, shouldn't it be 11.11m/s instead of 11.11m? It is one second of velocity instead of distance am I right?
@@TheAnswerKey @3:54 How did you get delta X = 11.11metre instead of 11.11metre/second since we are only doing subtracting on this part(vs-vp) ? I'm a little confused on this part in terms of the units
@@chongychongy2208 delta x is distance and we measure distance in m. I did the velocity 11m/s times the time 1 sec so the seconds cancel you get just m. hopefully that helps.
Hi! Thanks for the great tutorial, I see the way my teacher does this problem is by plugging in the time variable as (t-1), can you explain why this also works? thanks!
hello, why did you put 37.5 m/s for delta X variables?

hi. im not quite sure to which point in the video u are referring to. Could you please give me a time stamp so i could help you better

@@TheAnswerKey i understand now! Thank you so much

because he didnt start to accelerate until after waiting for 1 sec
