Question

A block is given an initial velocity of 5.00 m/s up a frictionless 20degree incline. How far up the incline does the block slide before coming to rest?

Answer 1

here
vf =0
vo = 5m/s
a=g.sin(theta)
theta=20 degree
g=-9.8 m/s^2
s=?
use

s= [vf^2 - vo^2]/2a

Ans=1.4 m

Answer 2

Hey there, I did the same question but I got 3.78m as my final answer. I used the same calculation and values that you did too.

Answer 3

Yes my answer is also 3.73

Answer 4

The solution is correct but he/she used radians instead of degrees

Answer 5

If you got 3.78, chances are you dropped the 2 in the denominator. 2a, not just a. 1.4 is correct.
