Yes, that's right. I was making calculation mistakes while I was solving this problem. The answer is the value + 3 seconds. Thank you so much for your help!

40.278*3+40.278t = 22.222*3+22.222*t+1/2*2.5*t2 when I simplified this equation I got 1.25t2-18.056t-54.168=0 So I put this into the quadratic formula (-b+√b2-4ac)/2a and the answer was 16.99... I'm not really good with the calculations and stuff so I mostly rely on mathway (where they do the...

I'm constantly getting the numbers wrong:( But thank you for telling me the equations I'm using are right! I feel much better lol

I don't understand what you mean...? According to the question, the initial velocity of the police car is 80km/h and the initial velocity of the speeder is 145km/h.

I added 3 seconds because the variable t used in the equation was the time the police car began accelerating. Not since when the speeder passes the police car. And the answer wasn't 13 seconds either, so I thought it was because I forgot to add 3 seconds :(

I hope I do... At the moment it's like "I like the professor, but physics...? meh :P" I'm trying to get better though and it's a huge improvement from my high school years lol

Homework Statement Problem: A police car traveling at 80km/h is passed by speeder traveling at 145km/h. 3 seconds after the speeder passes, the police car starts accelerating at 2.5m/s2. How much time passes before the police overtakes the speeder (moving at a constant speed)? Variables...

Nice to meet you all! I'm not really good at physics but I like the professor so here I am lol
