Answer:

The weight of the object is 490 N.

Step-by-step explanation:

The two forces, F1 and F2 acting upon the object in the horizontal direction are shown in the image attached.

We know that the net force acting upon the body is the sum of all the forces acting upon it and is given as:

Net Force = F1 + F2

m*a = F1 + F2

Acceleration to the right is = 2.5 m/s²

m*(2.5) = 50 + 75

m = 125/2.5

m = 50 kg

Now, weight of an object = mg

W = mg where g is gravitational acceleration given as g = 9.8 m/s²

W = 50*9.8

W = 490 N

An object pulled to the right by two forces has an acceleration of 2.5 m/s2. The free-example-1
