Question

One of the rectangular components of a velocity of 100 km|hr is 50 km|hr. Find the other component.

Answer 1

50^2 + x^2 = 100^2

x^2 =10000-2500= 7500

x =

$\sqrt{3} \times 50$

Answer 2

Given that,

Resultant velocity, v = 100 km/h

One of the component of velocity, $v_1=50\ km/h$

To find,

The other rectangular component.

Solution,

The resultant of velocity of rectangular component is given by :

$v=\sqrt{v_1^2+v_2^2}$

$v_2$ is other component

$100=\sqrt{50^2+v_2^2}$

On squaring,

$10000=2500+v_2^2\\\\v_2=86.6\ km/s$

So, the other component of velocity is 86.6 km/h.
