What is the difference between a vector and a scalar?

Which of the following angles could be used to resolve a vector into two components?

A 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

Resolve 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

Which equation will resolve your resultant into a y-component?

A 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]

The slope of a v/t graph shows which of the following:

If you could measure the value of a slope on an x/t graph can directly show you which of the following:

What is the value of the area under a v/t graph? [blank_start]Displacement[blank_end]

A woman takes her car from rest at a stoplight to a speed of 25 m/s in 10.0 seconds. What is her acceleration? a = [blank_start]2.5[blank_end] m/s^2
