Think about what defines a scalar vs a vector.
Question 5.
A truck with a mass of 2000 kg is moving at 30 m/s, and a motorcycle is moving in the opposite direction at 400 kg and 20 m/s. Calculate and compare their momentum.
Show hintHide hint
Don't forget to account for direction when calculating momentum.
Question 6.
In a collision, a small car weighing 900 kg moving at 25 m/s hits a stationary larger car weighing 2500 kg. If they stick together after the collision, what is their combined velocity?
