MHT CET 2022 Physics question
A vehicle without passengers is moving on a frictionless horizontal road with velocity 'u' can be stopped in a distance 'd'. Now 40% of it's weight is added. If the retardation remains same, the stopping distance at velocity 'u' is
Answer: (C)
Solution
For uniform retardation , the equation with final speed gives the stopping distance . This depends only on the initial speed and the retardation , not on the mass. Adding 40% more weight does not change
