Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

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.
