Ayoung woman named kathy kool buys a sports car that can accelerate at the rate of 5.37 m/s 2 . she decides to test the car by drag racing with another speedster, stan speedy. both start from rest, but experienced stan leaves the starting line 0.94 s before kathy. stan moves with a constant acceleration of 4.12 m/s 2 and kathy maintains an acceleration of 5.37 m/s 2 . find the time it takes kathy to overtake stan. answer in units of s.

As the stan moves 0.94 s before with an acceleration 4.12 m/s^2

so the distance moved by it

speed gained by the car is given as

now the relative speed of them is given as

relative acceleration is given as

now the distance between them is to be covered

by solving above equation we have

so it will overtake after 6.64 s

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
