A truck proceeds to be able to pass another truck. Its speed increases from 50 to 100 km/h in 4 seconds. What is its average acceleration?
Initial Velocity = 50 Km/hour = 0.014 Km/sec.
Final Velocity = 100 Km/hour = 0.028 Km/sec
Time duration = 4 Sec.
"Average Acceleration = \\frac{Final Velocity - Initial Velocity}{Time Duration}"
"Average Acceleration = \\frac{100 - 50}{4\/3600}"
On solving, we get
Average Acceleration = 45045 Km/hour sq. = 12.5 Km/sec. sq.
