Answer 2

To calculate the time it will take for you to intercept your friend, we can use the formula:

Time = Distance / Relative Speed

First, let's calculate the distance between you and your friend. Since your friend is directly in front of you, the distance between you is the same as the distance your friend has already traveled. We can calculate this using the formula:

Distance = Speed * Time

where the speed is the friend's speed and the time is the time it takes for you to intercept your friend.

Given: - Your friend's speed = 1.87 m/s [N] - Your speed = 2.79 m/s [N]

Let's assume the time it takes to intercept your friend is t.

The distance your friend has traveled is: Distance = (1.87 m/s) * t

The distance you have traveled is: Distance = (2.79 m/s) * t

Since you are trying to catch up to your friend, the distance you have traveled should be equal to the distance your friend has traveled. Therefore, we can equate the two distances:

(1.87 m/s) * t = (2.79 m/s) * t

Now, we can solve the equation for t:

(1.87 m/s) * t - (2.79 m/s) * t = 0

t * (1.87 m/s - 2.79 m/s) = 0

t * (-0.92 m/s) = 0

Since the speed cannot be negative and we are looking for the time it takes for you to intercept your friend, we can ignore the solution where t = 0. Therefore, we divide both sides of the equation by -0.92 m/s to solve for t:

t = 0 / -0.92 m/s

The time it will take for you to intercept your friend is 0 seconds.

However, it is important to note that this result implies that you are already directly in front of your friend at the beginning. If you are not already directly in front of your friend, the time it takes to intercept will be different.
