Answer:

m = 5 [kg]

Explanation:

To solve this problem we must use Newton's second law, which tells us that the sum of forces in a body must be equal to the product of mass by acceleration.

ΣF = m*a

Where:

F = force [N]

m = mass [kg]

a = acceleration = 4 [m/s^2]

Now replacing:

50 - 30 = m*(4)

m = 5 [kg]
