What is the weight of the object?
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.
50 n
98 n
313 n
490 n
f = 50 n
f = 75 n

b would be the answer

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

i think it would be 5
