The velocity - time graph for two bodies A and B are shown. Then the acceleration of A and B are in the ratio:
Options
- A( 25^ ) to ( 40^ )
- B( 25^ ) to ( 50^ )
- C( 25^ ) to ( 50^ )
- D( 25^ ) to ( 50^ )
Correct answer
B. ( 25^ ) to ( 50^ )
Step-by-step solution
Acceleration, ( a= d v d t ) ( a= ) slope of velocity ( - ) time graph Therefore, acceleration ( = ) For body ( A , a_ A = 25^ ) For body ( B , a_ B = 50^ ) Therefore, ratio ( a_ A a_ B = 25^ 50^ )
