hello,
I am a community college student who recently got accepted to transfer to UCSC and UCSD. However, i was uncertain what to study, and chose two different majors. AT Santa Cruz I got accepted into the bioengineering program, while at San Diego i am majoring in enviromental engineering...
y''-y'-30y=ln(t)
My attempt:
i tried to use the method of undetermined coefficients.
y''-y'-30y=ln(t)
Y(t)=A lnt
Y'(t)=A/t
Y''(t)= -A/t^2
I also tried:
Y(t) = A ln(t) + B 1/t + C 1/t^2
now I am stuck...any help??
Sphere/disk rolling down an incline HELP!
Homework Statement
a ball, or sphere with a radius of R and mass Mis rolling down an incline with a height of H and an angle of \Theta how long does it take to get to the bottom
Homework Equations
Conservation of mechanical energy
Kf +...
so then i come up with y_2 = x tan \theta - \frac {4.9x^2}{(v_0^2)(cos /theta^2)} if i set that equal to x tan \phi , i can simplify to tan \phi = tan \theta - \frac {4.9x}{(v_0^2)(cos^2 \theta)}
what would i do next??
A ball is hit at an angle \theta to the horizontal, from the base of a hill \phi degrees in incline. The ball strikes the hill at a horizontal distance x measured from the launch point. Determine the value of \theta that will result in the largest possible value of x .
well i started out...
