A small asteroid of mass 1105 kg is orbiting a planet that has a mass 3.52 x10^23 kg. What is the radial distance between the asteroid and the planet if the tangential velocity of the asteroid is 0.034 m/s?

How much work would it take to move a coulomb charge across a 4 volt potential difference?

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.

Aman jogs at a velocity of 2.5 m/s west for 1,200 s. he then walks at a velocity 1.0 m/s east for 500 s and then stops to rest . what is the displacement of man when he stops to rest?
