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.
