Answer:

Therefore, the cyclist take him to bike 2.5 seconds.

Step-by-step explanation:

The problem want us to solve for Time. Since, it has acceleration we can rewrite the formula of acceleration to time formula:

Where we have

• t = ?
• Initial Velocity = 18 m/s
• Final Velocity = 0
• a = 7.0 m/s²

Substitute it to the formula to calculate the time.

Therefore, the cyclist take him to bike 2.5 seconds.
