I pull my child in a sled over the snow. the rope makes an angle with the horizontal so that the pulling force has a horizontal component of 15 n and a vertical component in the upwards direction 25 n . the combined weight of the child and sled is 95 n . i'm getting tired and so the sled is slowing at a constant rate of 0.80 m/s each second.

Explanation:

The angle made by the rope to the horizontal (x)

⇒ sin X = 25/95

X= sin^-1(25/95)

X = 15.25
