A particel takes 8 s a to travel from A to B through P (sec the figure given below) and anothr particel travelling through Q takes 7s. Findt the speed and velocity of each particle.

Explanation

For particle traelling through p,
`"Speed"=("distance travelled")/("Time")=(7+6)/(8)=(13)/(8) m s^(-1)`
`"Velocity"=("Displacement")/("time")=(10pi)/(4)=(5pi)/(2) m s^(-1)`
Fot particle traveling through Q
Speed `=(6+8)/(7)=(14)/(7)`
`2 ms^(-1)`
Velocity `=(10)/(7) m s^(-1)`
