Answer:
Given: Distance = 60 meters, Time = 0.5 seconds
RTF: Find speed
Formula: speed = distance / time
Solution: speed = 60 meters / 0.5 seconds
speed = 120 meters/second
Answer: The speed of the baseball is 120 meters/second.
Given: Distance = 10 km, Time = 3 hours, Direction = west
RTF: Find velocity
Formula: velocity = distance / time, including direction
Solution: velocity = 10 km west / 3 hours
velocity = 3.33 km/hour west (rounded to two decimal places)
Answer: The velocity of the motorcycle is 3.33 km/hour west.
Given: Initial velocity = 8 m/s north, Final velocity = 23 m/s north, Time = 3 seconds
RTF: Find acceleration
Formula: acceleration = (final velocity - initial velocity) / time
Solution: acceleration = (23 m/s north - 8 m/s north) / 3 seconds
acceleration = 15 m/s north / 3 seconds
acceleration = 5 m/s² north
Answer: The wind's acceleration is 5 m/s² north.
