Constant Speed Calculations
100

What are the three types of motion?

At Rest, Constant Speed, Acceleration

100

A car is moving with a constant speed of 30 meters per second. What is its average speed after 40 seconds of motion?

30 m/s

200

You are sitting at your desk. What type of motion is this?

At rest

200

A cyclist rides 4000 meters in 3 minutes. What is the average speed of the cyclist?

vavg = d/t

vavg = (4000 m) / 180 s

vavg = 22.2 m/s

300

A ball is rolling down a ramp. What state of motion is this?

Acceleration

300

A car moves at an average speed of 30 meters per second for 20 minutes. How far did the car travel?

vavg = d/t

30 m/s = d/(1200s)

d = 36000 m

400

What is the difference between instantaneous speed and average speed?

Average speed is a measurement over time that summarizes the speed of an object. Instantaneous speed is an object's speed in a specific moment.

400

A boat is moving at a constant speed of 15 meters per second. How long does it take for the boat to travel 1000 meters?

vavg = d/t

15 m/s = (1000 m)/t

d = 66.7 seconds

500

A car has zero acceleration. What is/are the possible state(s) of motion of the car?

At rest and constant speed

Saturn orbits the sun at an average speed of 403 meters per second. It travels 374,515,315,200 meters during this orbit. How long does it take Saturn to orbit the Sun in years?

vavg = d/t

403 m/s = (374,515,315,200 m)/t

t = 929,318,400 s

years = 929,318,400 s / 60 s in a min / 60 min in an hr / 24 hrs in a day / 365 days in a yr

t = 29.5 years
