Q1
A body moves in a straight line with a uniform acceleration of 2 m/s². If its initial velocity is 5 m/s, what will be its velocity after 10 seconds?
25 m/s
20 m/s
15 m/s
10 m/s
Final velocity = initial velocity + acceleration * time = 5 + 2 * 10 = 25 m/s.

Q
Q: A body moves in a straight line with a uniform acceleration of 2 m/s². If its initial velocity is 5 m/s, what will be its velocity after 10 seconds?
Solution: Final velocity = initial velocity + acceleration * time = 5 + 2 * 10 = 25 m/s.
Steps: 8
Step 1: Identify the initial velocity of the body, which is given as 5 m/s.
Step 2: Identify the acceleration of the body, which is given as 2 m/s².
Step 3: Identify the time duration for which the body is moving, which is given as 10 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 m/s + (2 m/s² * 10 s).
Step 6: Calculate the acceleration part: 2 m/s² * 10 s = 20 m/s.
Step 7: Add the initial velocity to the calculated acceleration: 5 m/s + 20 m/s = 25 m/s.
Step 8: Conclude that the final velocity after 10 seconds is 25 m/s.
