Question

Rain is falling vertically downwards with a speed 5m/s . If unit vector along upward is defined as Jcap represent velocity of rain in vector form.​

Answer 1

-5j^ m/s

Explanation:

Given that,

Speed of rain = 5m/s

Velocity's direction is downwards that is opposite, so unit vector = -j^

As we know,

Velocity's magnitude is equal to the rain's speed. So,

Velocity of rain in vector form = magnitude × direction

= 5 m/s × -j^

= -5j^ m/s

Thus, the representation of velocity of rain in vector form would be -5j^ m/s
