Two cars of equal speed brake at the same time, but car A has three times the acceleration of car B.
Answer 1
________________________________________
Two cars of equal speed brake at the same time.
Initial speed of the car A = u
Final speed of car A = zero
Initial speed of the car B = u
Final speed of car B = zero
The acceleration of the car B = a.
The acceleration of the car A = 3a.
Time for car B = T
T = u/a
Time for car A = t
t = u/3a
t = T/3
Car A will take time T/3 to stop.
