I think I need some more help on that one. First of all how do I achieve 0 on the right side of the equation. Second how do I determine the variables?
And thank you for all your help! It seems like I lack some fundamentals in physics, heh...
Homework Statement
How much time does the object use to travel 12m down a plane. The object has a constant acceleration of 1m/s2 and the starting velocity is 5m/s.
Homework Equations
S=V(starting velocity)*t+1/2*a*t2
The Attempt at a Solution
Here I struggle with changing the formula. I could...
Since Englsih isn't my first language so I had a bit of a hard time to understand, but I think I got it.
F=m*g
F=10kg*9,78=97,8N
Then 25cm^2=0,4m^2
97,8 N per 0,4m^2
Pascal=97,8 N / 0,4m^2 = 244,5 Pa
Pascal=244,5
How is that?
