Answer:
The velocity is 31.25 m/s and direction is toward west.
Explanation:
Given that,
Distance
Magnetic field
Mass of proton
Radius of earth
Radius of orbit
We need to calculate the speed
Using formula of magnetic field
Put the value into the formula
Hence, The velocity is 31.25 m/s and direction is toward west.
Answer:
Explanation:
Acceleration is defined as the change in velocity divided by the time it took to produce such change. The formula then reads:
Where Vf is the final velocity of the object, (in our case 80 m/s)
Vi is the initial velocity of the object (in our case 0 m/s because the object was at rest)
and t is the time it took to change from the Vi to the Vf (in our case 0.05 seconds.
Therefore we have:
Notice that the units of acceleration in the SI system are (meters divided square seconds)
