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;

V = U + at

Where;

V is the final velocity. U is the initial velocity. a is the acceleration. t is the time measured in seconds.

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

$t = \frac{V - U}{a}$

Substituting into the equation, we have;

$t = \frac{55-30}{5}$

$t = \frac{25}{5}$

Time, t = 5 seconds.

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

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
