A particle is moving along a straight line and t seconds later it passes the point O of line at velocity V(m/s) where V=A- In(t+B) and A and B are positive constants. Also it is known that when t-10, the acceleration of the particle is - 1/20(m/s²) and that the particle comes to rest when t = 100 seconds. Find the exact value of B and A correct to two decimal places. ​
