Perpendicular vector components form a right triangle.
The resultant magnitude is found from the sum of squared components.
Choose an option to check your answer.
Slope gives change in velocity per unit time.
That is acceleration.
Choose an option to check your answer.
One kilometre equals 1,000 metres.
Therefore 3.5 km = 3.5×1,000 = 3,500 m.
Choose an option to check your answer.
Integrating velocity over time gives displacement.
Areas below the time axis count as negative displacement.

One metre equals 100 centimetres.
Therefore 250 cm ÷ 100 = 2.5 m.
Choose an option to check your answer.
Uniform acceleration means velocity changes by equal amounts in equal times.
The standard kinematic equations apply.
Choose an option to check your answer.
Percentage uncertainty is absolute uncertainty divided by measured value times 100.
0.2/10.0×100 = 2%.
Choose an option to check your answer.
Inertia is related to mass.
Greater mass means greater resistance to acceleration.
Choose an option to check your answer.
Percentage error is |48-50|/50×100.
The result is 2/50×100 = 4%.
Choose an option to check your answer.
Move the decimal four places to the right to obtain 7.2.
Therefore the exponent is -4.
