A particle is describing uniform circular motion in the anti-clockwise sense such that its time period of revolution is T. At t = 0 the particle is observed to be at A. If [{MathJax fullWidth='false' B_1 }] be the angle between acceleration at t = T/4 and average velocity in the time interval 0 - T/4 and [{MathJax fullWidth='false' B_2 }] be the angle b/w acceleration at t = T/4 and the change in velocity in the time interval 0-T/4, then the value of [{MathJax fullWidth='false' B_1 }] and [{MathJax fullWidth='false' B_2 }] are?

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue
