How much exertion in pounds does it take a woman who weighs 115 pounds to push a cart that weighs 50 pounds?

To calculate the amount of exertion required to push a cart, we need to consider the weight of both the woman and the cart. In this case, the woman weighs 115 pounds and the cart weighs 50 pounds.
To find the total weight, we need to add the weight of the woman and the cart: 115 pounds + 50 pounds = 165 pounds.
So, the total weight the woman has to push is 165 pounds.
Now, let's assume that the woman is standing on a flat surface and pushing the cart horizontally, without any incline or friction.
According to Newton's second law of motion, the force required to push an object can be calculated using the formula:
Force (in pounds) = Mass (in pounds) x Acceleration (in feet per second squared)
In this case, the mass of the object is the total weight of 165 pounds.
Now, assuming that the woman is pushing with a constant force, the acceleration would be considered zero since she is not trying to increase or decrease the speed of the cart.
So, the exertion or force required by the woman to push the cart that weighs 50 pounds would be 165 pounds.
