A proton (mass = 1.67 x 10-26 kg charge = 1.60 x 10-19 C) is running at a speed of 8.50 x 104 m/s at a point in an evacuated region of space where the electric potential is 35.0 volts. No force however the force of the electric field characterized by the electric potential acts on the proton. The particle moves to a point in the evacuated region of space where the electric potential is 47.0 Volts. What is the speed of a particle at that point in space?
A 2.1 kg block slides along a horizontal surface with a coefficient of kinetic friction μ k = 0.31. The block has a speed v = 1.4 m/s when it strikes a massless spring head-on.
Consider a person having mass M and holding two balls every of mass m is at rest over a frictionless surface. Now the person throws one ball towards right direction with velocity "
