A moving car accelerates from 30 mi / h to 80 km / h in 8 seconds. Find the average acceleration in units of m / s2. Make the necessary conversions before solving.
Added by Elizabeth M.
Step 1
Given: 30 mph 1 mile = 1.609 km 1 km = 1000 m 1 hour = 3600 seconds 30 mph = 30 * 1.609 km/h = 48.27 km/h 48.27 km/h * (1000 m / 1 km) * (1 h / 3600 s) = 13.41 m/s Therefore, the initial velocity is 13.41 m/s. Show more…
