Ответ:
Workdone = 2120 Joules.
Explanation:
Given the following data;
Force applied = 100N
Angle = 32°
Distance = 25m
To find the workdone by Steve, we would first of all find the horizontal component of the force applied.
Where;
Fx represents the horizontal force.
m is the mass of an object.
g is the acceleration due to gravity.
d is the angle of inclination (theta).
mg = weight = 100N
Substituting into the equation, we have;
Fx = 84.80N
Workdone is given by the formula;
Substituting into the equation, we have;
Workdone = 2120 Joules.
