Question

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 1

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

Step-by-step 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;

`t =(X)/(u_x)`

where;

`u_x` is the horizontal component of the velocity = uCosθ

`t =(X)/(u Cos \ \theta) \\\\t =(50)/(25 * Cos(45)) \\\\t= (50)/(17.678) \\\\t = 2.83 \ s`

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