Two particles A and B start from the origių
and travel in opposite directions along the circular
path of radius 5.0 m at constant speed of0.7 m/
s and 1.5 m/s respectively. Determine the time
when they collide and the magnitude of the
acceleration of B just before this happens.​

Answer:

14.3 sec

Explanation:

Total Distance Covered = 2πR

= 2 * (22/7) * 5

= 220/7  m

Speed of A = 0.7 m/s

Speed of B = 1.5 m/s

Total Speed = 0.7 + 1.5 = 2.2 m/s

Speed = Distance / Time

=> Time = Distance/Speed

Time = (220/7)/(2.2)

=> Time = 100/7  sec

=> Time  = 14.3 sec
