How much work is done in holding a 15 N sack of potatoes while waiting in line at the
grocery store for 3 minutes?

The work done in holding a 15 N sack of potatoes while waiting in line at the

grocery store for 3 minutes is 0.

Work done by a force is equal to the product of the magnitude of applied force and the distance through which the body moves.

Mathematically,

Work done = Fd

where

F = force

d = displacement

Therefore, for work to be done there must be an appreciable displacement .

But the person carried the sack of potatoes and stood at a spot. This means the work done = 0.

In other words there is no work done.

2700 Joules

Explanation:

Given variables are:

Workdone (w) = ?

Weight of sack (w) = 15N

Time taken (t) = 3 minutes

The standard unit of time is seconds, so convert 3 minutes to seconds

(If 1 minute = 60 seconds

3 minutes = 3 x 60 = 180 seconds)

Recall that work is done is when force is applied on an object over a distance

i.e Workdone = force x distance.

(However, the force acting on the sack of potatoes is weight)

Hence, workdone = weight x time

w = 15N x 180 seconds

w = 2700 J

thus, 2700 joules of work was done.

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?
