I am riding my bike at 25 m/s, I start to slow down at a rate of -4 m/s2. I slow down for 5 seconds... what is my final velocity?

The final speed of the bike is 5 m/s.

What is velocity?

Speed is  measured as the ratio of distance to the time in which the distance was covered.

To calculate the final velocity, we use the formula below.

Formula:

v = u+at................ Equation 1

Where:

  • v = Final velocity
  • u = Initial velocity
  • a = Acceleration
  • t = Time.

From the question,

Given:

  • u = 25 m/s
  • a = -4 m/s²
  • t = 5 seconds

Substitute these values into equation 1

  • v = 25+(-4×5)
  • v = 25-20
  • v = 5 m/s

Hence, the final speed of the bike is 5 m/s.
