You kick a soccer ball at a initial speed of 28 m/s at a 79 degrees angle above the ground. Calculate the horizontal distance when the ball touches the ground?

Sorry if you don´t understand something, english is not my first language

Approximately #30# m.

Explanation:

The horizontal range of a projectile (neglecting air resistance) is given by the formula #R=((v_0)^2sin2theta)/g# where #R# is the range, #v_0# is the initial velocity, #theta# is the angle of projection and #gapprox9.81ms^-2# (acceleration due to gravity).

So, #R=(28^2timessin(2times79))/9.81approx29.9#
