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 accelerates 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

3.504 m

Explanation:

Given that:

The speed (u)= 2.95 m/s

The acceleration = -0.876 m/s²

TIme t = 1.54 s

The length of the incline can be estimated by determining the distance traveled which can be achieved by using the second equation of motion.

`S = ut + (1)/(2)at^2`

`S = 2.95 (1.54) + (1)/(2)(-0.876) (1.54)^2`

S = 4.543 - 1.039

S = 3.504 m

Thus, the length of the incline = 3.504 m
