Answer 2

Problem Analysis

We are given that an object is moving with a constant acceleration and an initial velocity of 20 m/s. It travels a distance of 50 m in the first 2 seconds. We need to find the final velocity of the object after an additional 4 seconds of motion.

Solution

To solve this problem, we can use the equations of motion. The equation that relates distance, initial velocity, final velocity, acceleration, and time is:

distance = initial velocity * time + (1/2) * acceleration * time^2 We are given the initial velocity, time, and distance, and we need to find the final velocity. Rearranging the equation, we get:

final velocity = (distance - initial velocity * time) / time Substituting the given values, we have:

final velocity = (50 m - 20 m/s * 2 s) / 2 s

Calculating this expression, we find:

final velocity = 10 m/s.

Therefore, the final velocity of the object after an additional 4 seconds of motion is 10 m/s.

Conclusion

The final velocity of the object after an additional 4 seconds of motion is 10 m/s.
