Question

two cars start from the same point at rest . one within acceleration of 1.8 metre per second square whereas the other with an acceleration 3.2 metre per second square find the time after which their separation will become thousand metres also find the velocity at instantl​

Answer 1

Answer:

T=20 seconds

Explanation:

ANSWER

Let's take the two cars as A&B

Let distance covered by A be S  1​    

Let distance covered by B be S  2

B will catch A when S 1  =S  2  

S=ut+1/2×a×t  

2  

Therefore from given data,

40t+(1/2×0×t  2  )=0t+1/2×4×t  

2

 

40t=2t  

2

 

20t=t  

2

 

t=20s
