Sagot :
Statement:
A person is running at an initial velocity of 3.7 m/s. If the person is accelerating at 2 m/s².
To find out:
The person's final velocity after 3 s.
Solution:
- Initial velocity (u) = 3.7 m/s
- Acceleration (a) = 2 m/s²
- Time taken (t) = 3 s
- We know, the equation of motion,
- v = u + at
- Putting the values in the above equation, we get,
- v = 3.7 m/s + 2 m/s² × 3 s
- or, v = 3.7 m/s + 6 m/s
- or, v = 9.7 m/s
Answer:
The final velocity is 9.7 m/s in the direction of the motion.
