Question

A body is projected with a velocity 10i+20j. Find initial velocity, initial horizontal velocity, initial vertical velocity??

Answer 1

Explanation:

initial velocity = (10^2+20^2)^1/2 = 10(5)^1/2 m/s

initial horizontal velocity is the i component of velocity

= 10 m/s

initial vertical vvelocity is the j component of velocity

=20 m/s
