Question

A person is running at an initial velocity of 3.7 m/s. If the person is accelerating at 2 m/s2, what is their final velocity after 3 seconds?​

Answer 1

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.
