A train starts from rest and reaches a velocity of 20 m/s in 10 seconds. What is the train's acceleration?
A train starts from rest and reaches a velocity of 20 m/s in 10 seconds. What is the train's acceleration?
Hint: Starting from rest means the initial velocity is 0 m/s.
4. A Soccer Ball Is Kicked
A soccer ball initially moves at 2 m/s. After being kicked, its velocity increases to 14 m/s in 3 seconds. What is the ball's acceleration?
5. A Motorcycle Accelerates
A motorcycle is traveling at 8 m/s. The rider accelerates, and the motorcycle reaches 28 m/s after 5 seconds. Calculate its acceleration.
6. A Bus Slows Down
A bus is moving at 24 m/s. The driver applies the brakes, and the bus slows to 12 m/s in 6 seconds. What is the bus's acceleration?
Hint: When an object slows down, its acceleration is negative if it continues moving in the same direction.
7. A Skateboarder Slows Down
A skateboarder is moving at 10 m/s. After applying the brakes, the skateboarder's velocity decreases to 4 m/s in 3 seconds. What is the skateboarder's acceleration?
8. An Airplane Takes Off
An airplane begins its takeoff roll from rest and reaches a velocity of 60 m/s in 12 seconds. What is the airplane's average acceleration during this time?
Hint: Starting from rest means the initial velocity is 0 m/s.
