Y = 42t - 16t^2
velocity = vt = dy/dt
= 42 - 32t
v(1) = 42 - 32
= 10 ft/s
Hope this helps
Answer:
Por lo tanto la expresión anterior se menciona que el trabajo mecánico es igual a los cambios de energía cinética del sistema mecánico. Trabajo mecánico y energía potencial. ... "Se realiza un trabajo sobre un cuerpo cuando este se desplaza o deforma por la acción de una fuerza" (definición de trabajo).
<span>The answer is 15 centimeters. The waves with the
smallest wavelengths (also highest
frequency) have the least capacity to diffract around objects hence have a
shadowing effect, behind the object, especially if the wavelength is small
compared to the object. This is also the reason why high-frequency electromagnetic waves do not have a good reach in mountainous
regions. </span>
Answer:
That statement is correct.
