They did a flu shot from McKinnon at 45° to the horizontal with an initial speed of 25 m/s and that is positioned at a horizontal distance of 50 m from the canyon from which it is shot how long does it take the daredevil to travel the 50 m horizontally

Answer:

The time taken for the daredevil to travel the 50 m horizontally is 2.83 s.

Explanation:

Given;

angle of projection, θ = 45°

initial speed of the projectile, u = 25 m/s

horizontal distance traveled by the projectile, x = 50 m

The time taken for the daredevil to travel the 50 m horizontally is calculated as;

[tex]t =\frac{X}{u_x}[/tex]

where;

[tex]u_x[/tex] is the horizontal component of the velocity = uCosθ

[tex]t =\frac{X}{u Cos \ \theta} \\\\t =\frac{50}{25 \times Cos(45)} \\\\t= \frac{50}{17.678} \\\\t = 2.83 \ s[/tex]

Therefore, the time taken for the daredevil to travel the 50 m horizontally is 2.83 s.
