Learning goal: to be able to calculate work done by a constant force directed at different angles relative to displacement

if an object undergoes displacement while being acted upon by a force (or several forces), it is said that work is being done on the object. if the object is moving in a straight line and the displacement and the force are known, the work done by the force can be calculated as

w= f*s=/f/ /s/ cosθ

,

where w is the work done by force f on the object that undergoes displacement s directed at angle θ relative to f .

note that depending on the value of cosθ, the work done can be positive, negative, or zero.

Woke done, W = 4156.92 Joules

Explanation:

The work done by the force can be calculated as :

is the angle between force and the displacement

It is assumed to find the work done for the given parameters i.e.

Force, F = 30 N

Distance travelled, s = 160 m

Angle between force and displacement,

Work done is given by :

W = 4156.92 Joules

So, the work done by the object is 4156.92 Joules. Hence, this is the required solution.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

god i hope this !
