Chapter 5 & 6 Test this week!

#1 Speed/Velocity = ??? Distance = 75 km Time = 1.5 hrs Speed = Distance/Time 75km/1.5hrs = 50 kmh

#2 Speed/Velocity = ??? Distance = 3,000 mi Time = 5.0 hrs Speed = Distance/Time 600mph = 3,000mi/5hrs

#3 Speed/Velocity = ??? Distance = 4 km Time = 45 min =.75 hrs Speed = Distance/Time 4km/.75hrs = 5.33 kmh

#4 Speed/Velocity = 120mph Distance = ??? Time = 3.5 hrs Distance = Speed x Time 120mph X 3.5 = 420 miles

#5 Speed/Velocity = 55 kmh Distance = 200 km Time = ??? Time = Distance/Speed 200 km /55kmh = 3.63 hours

#6 Speed/Velocity = 100kmh Distance = 750 km Time = ??? Time = Distance/Speed 750 km /100 kmh = 7.5 hours

#7 Speed/Velocity = 1200 kmh Distance = ??? Time = 2.5 hrs Distance = Speed x Time 1200 kmh X 2.5 = 3,000 km

#8 Speed/Velocity =.10 km/min Distance = ??? Time = 2 hrs = 120 mins Distance = Speed x Time. 10 km/min x 120 mins = 12 km

#9 Speed/Velocity = 1 cm/s =.01 m/s Distance = 50 m Time = ??? Time = Distance/Speed 50 m/.01 m/s = 5000 seconds 5000/60 = minutes 83.33/60 = 1.38 hours.38 x 60 = 22.8 minutes.8 x 60 = 48 seconds 1 hour, 22 minutes, 48seconds

#10 Speed/Velocity = 5 kmh Distance = 16 km Time = ??? Time = Distance/Speed 16 km /5 kmh = 3.2 hours.2 x 60 = 12 minutes 3 hours and 12 minutes

Acceleration Acceleration = Final Velocity – Initial Velocity Time
