An object moves in a straight line with an initial velocity of 5 m/s and accelerates at 2 m/s². What will be its velocity after 4 seconds?

An object moves in a straight line with an initial velocity of 5 m/s and accelerates at 2 m/s². What will be its velocity after 4 seconds?

Step 1: Identify the initial velocity of the object, which is 5 m/s.
Step 2: Identify the acceleration of the object, which is 2 m/s².
Step 3: Identify the time over which the object accelerates, which is 4 seconds.
Step 4: Use the formula for final velocity: final velocity = initial velocity + (acceleration * time).
Step 5: Substitute the values into the formula: final velocity = 5 + (2 * 4).
Step 6: Calculate the acceleration part: 2 * 4 = 8.
Step 7: Add the initial velocity to the result: 5 + 8 = 13.
Step 8: Conclude that the final velocity after 4 seconds is 13 m/s.

Kinematics – The study of motion, specifically how velocity, acceleration, and time relate to each other.
Equations of Motion – Using the formula for final velocity in uniformly accelerated motion: final velocity = initial velocity + (acceleration * time).
