Julietta and Jackson are playing miniature golf. Julietta's ball rolls into a long. straight upward incline with a speed of 2.95 m/s and decelerates at -0.876 m/s/s for 1.54 seconds until it reaches the top of the incline and then continues along an elevated section. Determine the length of the incline.

Respuesta :

Answer:

The correct response will be "3.505".

Explanation:

The given values are:

Speed,

a = -0.876 m/s²

Decelerates at,

μ = 2.95 m/s

Time,

t = 1.54 seconds

As we know,

⇒ [tex]s= \mu t+\frac{1}{2}at^2[/tex]

On substituting the given values in the above expression, we get

⇒    [tex]=2.95\times 1.54-\frac{1}{2}\times 0.876\times (1.54)^2[/tex]

⇒    [tex]=4.543 - 1.038[/tex]

⇒    [tex]=3.505[/tex]
