e) None of the above. sele 13 When a 1984 Alfa Romeo Spider sports car accelerates in the x-direction at the maximum Þóssible rate, its motion during the first 20. seconds is extremely well modeled by the simple equation vx = (60 m/s)t, where t is time in seconds and vz is in m/s. In other words, the square of the car's velocity increases linearly with time. What is its acceleration after 3s, assuming that the car starts from rest at t = 0 s? 2 3 %3D a) 6.7 m/s2 b) 2.0 m/s2 c) 7.2 m/s² d) 2.2 m/s² e) 2.7 m/s2

hi ! can u write the solutions legibly ? and explain it if possible, thank you so much <3

Kindly answer the subparts ,d,e & f of this question based on the passage in a clear handwriting with details.(Don't just write the formulas. Give the explanation of the formulas and the calculation along with it) I am providing the full question because the whole question is related. These are not seperate questions. It is only a whole question. kindly solve the questions following the given instructions of the question with mentioning the subpart's number as 'd' , 'e' and 'f'. Kindly check the answer before providing it to me as it is my fifth post of this question. I have got wrong answers in the previous uploads.

For example, for the equation r TV, if G = y and V = x, what represents m? If we solve for G, then G = rTV = (rTt)V. We have now put it in the form of y= (m)* x. Writing it like this, we can easily identify rTt as the slope m. a) For the equation: Rx = = Rk b) For the equation: VAB = R₁ -Vo if Rx 1 1+ R2 2 = y and R₂ = x, what is m? ARx, if VAB = y and ARx Rk = x, what is m?

This is third time that I post it all the given answers was wrong and all  was chat gpt or ai answers that I have no need.  plz give me complete solution with 100 % accuracy don't use chat gpt or ai plz plz plz . I definitely upvote for your best answer .

Kindly give me a detailed answer in a clear handwriting of subpart (b). I am attaching the full question but I only need (b). All the questions are related. I only have few minutes kindly give the ans ASAP. I will upvote if the answer is correct and answered soon. Thank you.

Q2: Use dimensional analysis to determine which of the following equation is certainly wrong: mu v (2gh)2 Where 2 and h are the lengths and | F] = [ MLT1. The other symbols have their usual meaning?

Use a scientific calculator to calculate Delta L_fS for D1 = 20 meters and D2 = 40 meters.  I can't believe I have to ask this, but I can't even figure out how to input that in the calculator.

Solve it correctly please. I will rate accordingly. This is my last attempt.. multiple votes will be done.

I'm having some issues understanding my physics homework. It doesnt look like what we were doing in class and I dont think I'm using the right formulas. I need some help with a & b, attached.
