Question

9. If a car speeds up from a standing start to 100m/s in 5 seconds , what is its acceleration (in m/s^2)
10. Correlate the following
a. Distance:scalar,velocity:?
b. Speed:km/h,acceleration:?

Answer 1

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
