When a football in a field goal attemp reaches its max height how does its speed compare to its inital speed?
a)it's zero
b) it is less than its inital speed
c)it is equal to its inital speed
d)it is greater than its inital speed
since at the max height v=0 isn't the answer a)?
the speed at the maximum hieght would be zero
Well, if at the max height the speed is zero...
the speed at the max height must be less than the initial velocity
so i think (b) is the answer.
Yes, you are correct. At the maximum height of a football during a field goal attempt, its vertical velocity (speed) is zero. Therefore, the correct answer is a) it's zero.
Yes, you are correct. When a football reaches its maximum height during a field goal attempt, its vertical velocity (speed) is indeed equal to zero. Therefore, the correct answer is option (a) - it's zero.
To further explain, in the case of projectile motion (such as a football being kicked), the vertical velocity decreases gradually as the ball moves upward against the force of gravity. At the maximum height of the ball's trajectory, its vertical velocity becomes zero because it has reached its peak and is about to start coming back down.
The initial speed of the football refers to the speed at which it was kicked or launched. As the ball goes up, its speed gradually decreases due to the opposing force of gravity. And at the maximum height, this decrease in speed results in the vertical velocity becoming zero.
