A soccer player kicks a ball from ground level with an initial velocity of 25 m/s at an angle of 30° above the horizontal. In all calculations, treat gravitational acceleration as g = 10 m/s2.
What is the highest point in meters that the ball will reach?
Could someone explain this in detail of how to get the answer?
In some Rutherford scattering experiments, the alpha particles had kinetic energies of 7.7MeV
assume two cans of differently coloured paint at the same temperature can be mixed together adiabatically. the second law of thermodynamics is simply not relevant to this situation
what is the velocity of plane with respect to the ground. A nonconducting sphere has radius R = 2.53 cm and uniformly distributed charge q = +6.00 fC. Take an electric potential at the sphere's center to be V0 = 0.
