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

Time, t = 10 seconds.

Step-by-step 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 = (v - u)/(a)`

Substituting into the equation, we have;

`t = (30 - 10)/(2)`

`t = (20)/(2)`

Time, t = 10 seconds.
