CBSEENPH11017998

One of the rectangular components of velocity of a particle is 12 m/s and the other is 16 m/s. What is the speed of the particle?

Solution

The rectangular components of velocity of a particle is 12 m/s and 16 m/s. 
Therefore, the velocity of the particle, v = square root of 12 squared plus 16 squared end root space equals space square root of 400 space equals space 20 space m divided by s
