Explanation:
Downstream: you just sum the magnitude of the velocity vectors:
3km/h + 4km/h = 7km/h
Upstream: difference of the magnitudes of the velocity vectors, in absolute value:
|3km/h - 4km/h| = 1km/h
Explanation:
It is given that,
The position of a particle is given by :
(a) Velocity of a particle is given by :
Putting values,
The acceleration of the particle is given by :
(b) At t = 0,
Velocity, v = 6k m/s
Acceleration, a = 6i m/s²
