6)
ET AB BEX THEN BC IS 2X AND THE TOTAL DIS IS 3X
IF THE BODY IS MOVING WITH A CONSTANT ACC.
THEN R=THE ACC CAN BE FOUND OUT FROM THE FORMUA
V^2=U^2+2AS
V=25 U=5
A=100/X
TIME TAKEN TO REACH POINT B WHICH IS AT A DISTANCE X FROM POINT A CAN BE GIVEN FROM THIS FORMULA
S=UT+1/2AT^2
FROM THE TIME SO FOUND OUT WE CAN CALCULATE THE VELOCITY AT POINT B FROM THE FORMULA
V=U+AT
THEN POINT C IS AT A DIS 2X FROM POINT B
THE VELOCITY AT POINT B IS ALREADY TAKEN OUT
SO
TIME CAN BE TAKEN OUT FROM THE FORMULA '
S=UT+1/2AT^2
AND THUS THE RATIO OF THE TIME TAKEN CAN BE EXTRACTED
PLZ RATE ME IF U FIND ME USEFUL
