You hit a tennis ball with an initial vertical velocity of of 25 m/s. The ball leaves the tennis racket 2 meters above the ground. How much time does your opponent have before the ball hits the ground on the other side of the net, h(t)?

at least two

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
