How far did the vehicle travel during the first 2 seconds?

• 0.2 m
• 5 m
• 10 m
• 20 m

The rate at which velocity changes is called

• acceleration
• constant speed
• average speed
• displacement

2 objects traveling at the same speed have different velocities if they....

• start at different times
• travel different distances
• have different masses
• move in different directions

Speed=

• T/D
• D/T
• S x T
• D x T
