If an object is projected horizontally from a height of 5 m with an initial velocity of 7 ms What is the value of X0 A X0 98ms squared B X0 7 C X0 0 D X0 5 class=

Respuesta :

The horizontal distance traveled by the projectile is 7 m.

The given parameters;

height of the projection, h = 5 m

initial horizontal velocity of the projectile, v = 7 m/s

The time of flight of the projectile is calculated as;

[tex]h = v_0_yt + \frac{1}{2} gt^2\\\\5 = 0 + 0.5\times 9.8t^2\\\\5 = 4.9t^2\\\\t^2 = \frac{5}{4.9} \\\\t^2 = 1.02\\\\t = \sqrt{1.02} \\\\t = 1 \ s[/tex]

The horizontal distance traveled by the projectile is calculated as;

X = vt

X = 7 x 1

X = 7 m

Thus, the horizontal distance traveled by the projectile is 7 m.
