Question

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.

Answer 1

The correct response will be "3.505".

Step-by-step 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,

⇒
`s= \mu t+(1)/(2)at^2`

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

⇒
`=2.95* 1.54-(1)/(2)* 0.876* (1.54)^2`

⇒
`=4.543 - 1.038`

⇒
`=3.505`
