Topic: Kinematics

Subtopic: Projectile from Height

An object is projected horizontally from a 100 m high cliff with a speed of 10 m/s. What will be its velocity 1 second after projection?

10 m/s

20 m/s

10√2 m/s

10√3 m/s

Given:

$v_x = 10$

m/s,

$g = 10$

m/s²,

$t = 1$

Vertical velocity:

$v_y = g t = 10$

m/s

Resultant velocity:

$v = \sqrt{v_x^2 + v_y^2} = \sqrt{10^2 + 10^2} = 14.1 \text{ m/s}$
