11/8 Speed, Velocity, Distance and Time

Which of the following is an example of SPEED and NOT velocity:

• A car driving north at 60 miles per hour.

• Driving from California to Texas at 75mph.

• A ball thrown straight up and down.

• A car drving at 60 miles per hour.

Velocity is made up of which measurements:

• temperature, distance and time

• distance and time only

• distance, time and direction

• direction, distance and density

Three friends take a car trip. The car moves North 140km over a time of 2 hours, what is its velocity?

• 70km/hr

• 70km/hr North

• 280km//hr North

• 6km/hr North

What is the velocity: A car has a displacement of 150km to the south in 5 hrs.

• 15km/hr North

• 30km/hr North

• 30km/hr South

• 750km/hr East

A car turns East on a highway from point A to point B covering a distance of 50 kilometers in 0.5 hour. What is the velocity?

• 10km/hr East

• 100km/hr

• 100km/hr South

• 100km/hr East

Solve for SPEED: a city bus travels a distance of 10km in 0.5seconds

• 10km/s

• 5km/s

• 0.33km/s

• 20km/s

A snail's speed is 5mm/s. What is needed to know the velocity of the snail?

• Volume

• Distance

• direction

A spider travels across a driveway of 36cm at a speed of 14cm/s. How long does it take the spider to cross the driveway? Solve for TIME:

• 504sec

• 14 sec

• 2.6sec

• 0.39 sec

A motorist sets his cruise control to 80 miles/hr. How far will he travel in 15min (0.25hr)? HINT: you have to use the same units (miles and hours).

• 20miles

• 1,200miles

• 5.33 miles

• 320miles

A comet is cruising the solar system at 50,000kilometers per hr for 4hrs. What is the DISTANCE:
