Answer 2

To find the time it takes for the motorcycle to reach a speed of 5 m/s from an initial speed of 0.8 m/s, we can use the equation of motion:

v = u + at

where: - v is the final velocity (5 m/s), - u is the initial velocity (0.8 m/s), - a is the acceleration, and - t is the time.

Since we are given the initial velocity and the final velocity, we need to find the acceleration first. To do this, we can use the equation:

a = (v - u) / t

Rearranging the equation, we have:

t = (v - u) / a

Now, let's calculate the time it takes for the motorcycle to reach a speed of 5 m/s.

Calculation:

Given: - Initial velocity (u) = 0.8 m/s - Final velocity (v) = 5 m/s

We need to find the time (t).

First, let's calculate the acceleration (a):

a = (v - u) / t

Substituting the given values:

a = (5 - 0.8) / t

Simplifying:

a = 4.2 / t

Now, let's rearrange the equation to solve for time (t):

t = 4.2 / a

To find the value of acceleration (a), we need more information. Unfortunately, the search results did not provide any additional information to calculate the acceleration. Therefore, we cannot determine the exact time it takes for the motorcycle to reach a speed of 5 m/s without knowing the acceleration.

If you have any additional information or if there's anything else I can help you with, please let me know!
