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.

Text Solution

Verified by Experts

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