A football player is preparing to punt the ball down the field. He drops the ball from rest and it falls vertically 1.0 m down o
nto his foot. After he kicks it, the ball leaves the foot with a speed of 18.5 m/s at an angle 57° above the horizontal.
What is the magnitude of the impulse delivered to the ball in kilogram meters per second after he kicks it? An American football has a mass of 425 g.

Explanation:
Let f is the frequency of an oscillation and T is the period of the oscillation. There exists an inverse relationship between the frequency and the time period of the oscillation. Mathematically, it is given by :
Also,
So,
The time taken to complete one oscillation is called the period of the oscillation and the number of oscillation is called the frequency if an oscillation.
Answer:
Velocidad = 2 m/s
Explanation:
Dados los siguientes datos;
Distancia = 80 m
Tiempo = 40 s
Para encontrar la velocidad del automóvil;
La velocidad se puede definir como la tasa de cambio en el desplazamiento (distancia) con el tiempo.
La velocidad es una cantidad vectorial y, como tal, tiene magnitud y dirección.
Matemáticamente, la velocidad viene dada por la ecuación;
Sustituyendo en la fórmula, tenemos;
Velocidad = 80/40
Velocidad = 2 m/s
