Question

How much is work is done on a sled pulled 4.0m to the night by a force 75.0N at an angle of 350° above the horizontal​

Answer 1

295.44 J

Step-by-step explanation:

Here we use the formula for work; W = f.dcosθ

∴ f is force in Newtons, d is displacement in meters and θ is the angle made with the horizontal.

Substituting the values in the equation from the question:

W = 75 x 4 x cos(350)

W = 300 x cos(350)

W = 295.44 J
