Answer:
mass ratio of A/B is 2:1
Explanation:
Since the mass of box A = 10g
mass of box B = 5g
Mass of box C = mass of box A + mass of box
A ratio compares two quantities. To find the ratio of the two boxes:
Ratio of A to B =
Ratio of A to B = = 2
The mass ratio is 2:1 i.e box A has twice the mass of B
The change in the velocity = 4 m/s
Acceleration = 4 m/s²
<h3>Further explanation</h3>Given
vo = initial velocity = 4 m/s
vf = final velocity = 8 m/s
t = 1 s
Required
The change in the velocity
Acceleration
Solution
the change in velocity =
Acceleration = ratio of a change in velocity and the time
Input the value :
