Answer:
the scalar quantities in this exercise are: 3 kg rice, 2 liters of milk and 5 face masks, the rapides 3 m / s
the vector quantities are: the displacement to the supermarket and the drugstore
Step-by-step explanation:
For this problem we are asked to find scalar quantities and vector quantities.
A scalar quantity is one that is described by a number with its units
A vector quantity is that described by a number (module), a direction and a sense, that is, they must be represented by a vector
the scalar quantities in this exercise are: 3 kg rice, 2 liters of milk and 5 face masks, the rapides 3 m / s
the vector quantities are: the displacement to the supermarket module 50 m directional 30º sense with respect to the horizontal.
The displacement to the drugstore modulo 70 m direction 150º with respect to the supermarket
