A pine cone fell 240 centimeters straight down at a constant velocity. It fell that distance in 2.5 seconds. What was its velocity? In 1.8 hours, a sailboat sailed 81 kilometers east across the sea at a constant velocity. What was the sailboat’s velocity? A remote-controlled drone was 924 meters away from a large oak tree. It flew north at a constant velocity and reached the oak tree in 88.0 seconds. What was the drone’s velocity? A raindrop fell straight toward the ground at a constant velocity for 4.0 seconds. In that time, it fell 8.8 meters. While falling, the raindrop passed a flower petal that was falling at 1 meter per second. What was the raindrop’s velocity? Andrew was biking west at a constant velocity. He biked 840 meters, which took him 5.6 minutes. During that time, Andrew passed a woman walking at 54 meters per minute. What was Andrew’s velocity? 1. 2. 3. 4. 5. Find
1. The velocity of the pine cone can be found by dividing the distance it fell (240 cm) by the time it took to fall (2.5 seconds).
Velocity = Distance / Time = 240 cm / 2.5 s = 96 cm/s
2. The velocity of the sailboat can be found by dividing the distance it sailed (81 km) by the time it took to sail (1.8 hours).
Velocity = Distance / Time = 81 km / 1.8 h = 45 km/h
3. The velocity of the drone can be found by dividing the distance it flew (924 m) by the time it took to reach the oak tree (88.0 seconds).
Velocity = Distance / Time = 924 m / 88.0 s = 10.5 m/s
4. The raindrop's velocity can be found by dividing the distance it fell (8.8 m) by the time it fell (4.0 seconds).
Velocity = Distance / Time = 8.8 m / 4.0 s = 2.2 m/s
5. Andrew's velocity can be found by dividing the distance he biked (840 m) by the time it took him to bike (5.6 minutes, converted to seconds).
Velocity = Distance / Time = 840 m / (5.6 min * 60 s/min) = 2 m/s
