1What is the difference between a vector and a scalar?
- AVectors are longer
- BVectors are like scalars, but also include a magnitude

3A car is moving in a straight line at 50 m/s. How far will it have traveled in 10 seconds?
x = [blank_start]500[blank_end] m- A500
4Resolve the following vector into its components:
R = 100.0 m @ 45 degrees
x = + [blank_start]70.71[blank_end] m
y = + [blank_start]70.71[blank_end] m- A70.71
- B70.71

6A line is drawn to be 10.33 cm long at an angle of 10 degrees to the - y axis. What is the vector's y component?
The first blank is for the sign. The second blank is for the value. The third blank is for the units.
y = [blank_start]-[blank_end] [blank_start]10.17[blank_end] [blank_start]cm[blank_end]- A-
- B10.17
- Ccm

- BSpeed
- CDistance
- DDisplacement
- EAcceleration
9What is the value of the area under a v/t graph?
[blank_start]Displacement[blank_end]- ADisplacement
10A woman takes her car from rest at a stoplight to a speed of 25 m/s in 10.0 seconds. What is her acceleration?
