I don't know if you'll ever see this but thank you for taking the time to answer all 3 of my questions! I can't tell you enough how much it's helping me

Physics
CIRCULAR MOTION A car takes a curve with 300m radius at a velocity of 60 m/s. a) Determine the change in velocity (module and direction) when it travels an arc of 60 degrees b)Compare the magnitude of the instantaneous acceleration of the car with a magnitude of the average ac...

Physics
In a Bohr of a Hydrogen atom, an electron moves in a circle with a radius of 5.10(^-9) cm around a nucleus charged positive due to electrostatic force. What is the intensity of the force so that the electron has a velocity of 2.3 x 10(^8) cm/s? The mass of the electron is 9x10...

What angle (from earth) should one shoot a projectile so that it reaches it's maximum?

Physics
A particle moves with the acceleration a=2e(^-t)i+5cos(t)j In the instant when t=0 the particle is at the point r=i-3j with the velocity v=4i-3j. Calculate the velocity and position of the particle at any instant. I tried doing the problem and ended up just rearranging the for...
