A projectile is launched at an angle of 11.0° above the horizontal. What is its initial speed if it hits a target that is located a horizontal distance of 170 m from the launch point and 11.5 m above the launch level?
A projectile is launched at an angle of 11.0° above the horizontal. What is its initial speed if it hits a target that is located a horizontal distance of 170 m from the launch point and 11.5 m above the launch level?
If vo is the initial velocity, θ is the projection angle, g is the acceleration due to gravity, the vertical distance is y, horizontal distance is x, then the equation of motion of projectile is given by,
