Question

An object pulled to the right by two forces has an acceleration of 2.5 m/s2. The free-body diagram shows the forces acting on the object.

A free body diagram with 4 force vectors. The first vector is pointing downward labeled F Subscript g Baseline, the second pointing up labeled F Subscript N Baseline. The third pointing right labeled F Subscript 1 Baseline = 50 N the last is from the tip of the third using the tail to tip method labeled F Subscript 2 Baseline = 75 N pointing right.

What is the weight of the object?

50 N
98 N
313 N
490 N

Answer 1

Net horizontal force = 50 + 75 = 125 N.
m = Fnet / a = 125 / 2.5 = 50 kg.
Weight = mg = 50 × 9.8 = 490 N.

Answer: 490 N.
