Question

it took 50 joules to push a shopping cart 5 meters. With what force was the shopping cart pushed?

Answer 1

joules equal to force / length.

joules unit is N/m

force unit is N

length unit is m

hence ,

50x5 = 250 N/m

force = 250 N/m.

Answer 2

The force with which the shopping cart is pushed is 10 N.

Explanation:

Given that,

Work done to push a shopping cart, W = 50 J

Distance, d = 5 m

We need to find the force with which the shopping cart is pushed. We know that the work done by an object is given by the formula as:

$W=F\times d\\\\F=\dfrac{W}{d}\\\\F=\dfrac{50\ J}{5\ m}\\\\F=10\ N$

So, the force with which the shopping cart is pushed is 10 N. Hence, this is the required solution.
