Answer:
Time taken for the car to travel a distance of 4.50 m = 1.40 seconds
Explanation:
velocity of toy car = 3.21 m/s
distance travelled by toy car = 4.50 m
Time = ?


Therefore, the time taken for the car to travel a distance of 4.50 m = 1.40 seconds

No force contributes to density, the density is a physical quantity that is defined as being

the raport between the mass of the object and its volume. However if you want to measure the density of an object you might want to determine its gravity force (weight)

from which knowing the gravitational acceleratin you can find its mass
