Q: A tennis player serves the ball at a speed of 180 km/h. What is this speed in meters per second? (2023)
Solution:
To convert km/h to m/s, divide by 3.6. Speed in m/s = 180 km/h ÷ 3.6 = 50 m/s.
Steps: 6
Show Steps
Step 1: Understand that we need to convert kilometers per hour (km/h) to meters per second (m/s).
Step 2: Know the conversion factor: 1 km/h is equal to 1/3.6 m/s.
Step 3: Take the speed of the tennis player, which is 180 km/h.
Step 4: Divide 180 by 3.6 to convert it to m/s: 180 ÷ 3.6.
Step 5: Calculate the result: 180 ÷ 3.6 = 50.
Step 6: Conclude that the speed of the tennis player in meters per second is 50 m/s.
