Question

how much time does a bike with an acceleration of 2ms2 takes to increase its velocity from 10ms-2 to 30ms-2​

Answer 1

Answer:

Time, t = 10 seconds.

Explanation:

Given the following data;

Initial velocity, u = 10 m/s

Final velocity, v = 30 m/s

Acceleration, a = 2 m/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;

$t = \frac{30 - 10}{2}$

$t = \frac{20}{2}$

Time, t = 10 seconds.
