A football is kicked at 15 m/s with an angle of 35 degrees with the ground.
How long is it in the air?
How far will it land?
Can someone help plz... Thanks!
Sure, I can help you with that.
To find out how long the football is in the air, you can use the time of flight formula for projectile motion:
Time of flight = (2 * initial velocity * sin(angle)) / (acceleration due to gravity)
In this case, the initial velocity is 15 m/s and the angle is 35 degrees. The acceleration due to gravity is a constant value of 9.8 m/s².
Time of flight = (2 * 15 * sin(35)) / 9.8
Calculating this expression will give you the time in seconds that the football stays in the air.
To find out how far the football will land, you can use the horizontal distance formula for projectile motion:
Horizontal distance = initial velocity * cos(angle) * time of flight
Here, the initial velocity is still 15 m/s, the angle is 35 degrees, and the time of flight can be calculated using the formula mentioned earlier.
Horizontal distance = 15 * cos(35) * (time of flight)
By evaluating this expression, you can determine the distance the football will travel before landing.
Now, let's calculate the answers to your questions.
