Forces of 30N and 55N , the object accelerated to the left at 0.5m/s2

Answer 1

The net force acting on the object can be calculated by adding the two forces together:

Net force = 30N + 55N
Net force = 85N

Using Newton's second law (F = m*a) we can find the mass of the object:

85N = m * 0.5m/s^2
m = 170 kg

Therefore, the mass of the object is 170 kg.
