GOT it! thank you very much!

don`t i know the function from the V(t=0)=0 and the differential equation that i get from the integral Vy = ∫aydt (here i integrate a known function) ? i mean aren't these two thing enough?

sorry there is no 2. I have made a mistake when i was writing this post... and i copied it everywhere...

I saw this problem and solved it but still I had one question... Homework Statement A rock falls through water with a continuously decreasing acceleration. Assume that the rock’s acceleration as a function of velocity has the form ay = g - bvy where b is a positive constant. (The +y direction...

thank you very much for the help!

dx/dt = √( 2 * (x2 - 1)) → dt = dx/√(2(x2 - 1)) ... and i`m stuck with the math if i integrate here in an interval of 1 to 3 (both sides ) , won't i lose the t in the equation ?

Homework Statement Suppose the acceleration of a particle is a function of x, where a(x)=(2.0 s-2)*x. (a) If the velocity is zero when x= 1.0 m, what is the speed when x=3.0 m? (b) How long does it take the particle to travel from x=1.0 m to x=3.0 m. a(x)=(2.0 s-2) * x (a) V(x=3) = ? , V(x=1)...

thank you very much! I got the correct answer. <3 p.s. sorry that i didn't clarified what tb means

Homework Statement Ball A is dropped from the top of a building of height h at the same instant that ball B is thrown vertically upward from the ground. At what height will the balls collide if the collision occurs when the balls are moving in the same direction and the speed of A is 4 times...

Hi! I`m a student that needs some help with some physics problems. I study telecommunications and I`m a physics enthusiast. Looking forward to discussing physics problems with you all! :)
