Question

what was the final velocity/speed? (this should look familiar) * 1 point
40
40 m/s
40 n
40 kg
yeaahhhhhhh... you should have calculated how long it would take. what was the change in velocity/speed? * 1 point
40 m/s
40
40 kg
40 m/s^2

Explanation:

Velocity is a vector quantity and speed is a scalar quantity, both having the SI unit of m/s. Force is measured in Newtons (N) and mass in kilograms (kg). Acceleration is in m/s². For the first question, the correct unit - for velocity/speed is m/s. For the second question, change in velocity/speed has the same unit as velocity/speed which is m/s.

Answer:

First question: B. 40 m/s
Second question: A. 40 m/s
