a=(5.8-1.5)÷15.8
a=4.3÷15.8
a=0.27m/s
Explanation:
acceleration=final velocity - initial velocity /time
Answer:
white, blue and red
Explanation:
Force is given by
![F=ma](https://tex.z-dn.net/?f=F%3Dma)
where
m = Mass of object
a = Acceleration of the object
If the acceleration is same for all the cars the force needed to be applied will depend on the mass of the car. The heaviest car requiring the most force and the lightest car requiring the least amount of force.
Here, the weight of the cars in descending order is white, blue and red.
So, the cars in order from the most to least amount of force needed to move them is white, blue and red.

Answer:
Density = 0.111 g/cm^3
Explanation:
Given that
Make m = 40g
The given dimension are 30cm by 4cm by 3cm
Volume V = 30 × 4 × 3 = 360 cm^3
Density is the ratio of mass to volume.
That is,
Density = mass/volume
Substitute mass and volume into the formula
Density = 40/360
Density = 0.1111 g/cm^3
