A lorry and a car of mass ratio 4:1 are moving with KE in the ratio 3 : 2 on a horizontal road. Now brakes are applied and braking forces produced are in the ratio 1 : 2. Then the ratio of stopping timings of lorry and car is

A lorry and a car of mass ratio 4:1 are moving with KE in the ratio 3

1.	A lorry and a car of mass ratio 4:1 are moving with KE in the ratio 3 : 2 on a horizontal road. Now brakes are applied and braking forces produced are in the ratio 1 : 2. Then the ratio of stopping timings of lorry and car is
