A motorcyclist increases the velocity of his bike from 30.0 meters/second to 55.0 meter/second under a constant acceleration of 5.00 meters/second^2. How long does it take the bike to reach the final velocity?

Time, t = 5 seconds.

Explanation:

Given the following data;

Initial velocity = 30m/s

Final velocity = 55m/s

Acceleration = 5m/s²

To find the time, we would use the first equation of motion;

Where;

Making time, t the subject of formula, we have;

Substituting into the equation, we have;

Time, t = 5 seconds.

Therefore, it would take the bike 5 seconds to reach the final velocity.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
