You own a truck delivery business and have a customer that needs to send an overnight shipment of materials to a work site in another city. The package MUST arrive by tomorrow morning at 8:00 AM. Both cities are in the same time zone and are 1000 miles apart. The maximum speed that your truck can drive is 75 miles per hour and the earliest you could leave is 3:00 PM. Is it possible for you to make this trip and deliver the customer’s order? You must factor in 3 hours of time for breaks and refueling.
Write the equation for calculating the acceleration of an object.
A fish swimming at a constant speed of 0.5 m/s suddenly notices a shark appear behind it. Five seconds later, the fish is swimming in the same direction at a speed of 2.5 m/s. What was the fish’s average acceleration?
A driver is traveling eastward on a dirt road when she spots a pothole ahead. She slows her car from 14 m/s to 5.5 m/s in 6 s. What was the car’s acceleration?
Explain why velocity is more specific than speed.
Draw an example of a distance/time graph that shows constant speed.
If you know a car travels 30 km in 20 minutes, you can find it’s what?
Which has a greater speed, a heron that travels 600m in 60 seconds or a duck that travels 60m in 5 seconds? Show you work.
A family takes a car trip. They travel for an hour at 60km/h and then for 2 hours at 40km/h. Find the average speed during the trip.
Can an object have a constant speed and still be accelerating? Explain.
On a distance-versus-time graph, the slope of the line tells you what about the object’s motion?
1 meter = ______decimeters, ______centimeters, ______millimeters
100 centimeters = ______meters, ______millimeters, ______decimeters
1 kilometer = ______meters, ______hectometers, ______dekameters
The distance between the Earth and the Moon averages 384,403 km. Convert this distance to meters.
