Work done = Increase in kinetic energy
SO W = (1/2) m (v22 - v12)
So W = 12 x 5 x 3 = 180 J

How much work must be done on a 24 kg shopping cart to increase its speed from 1 m s to 4 m s?
Kinetic energy of a moving mass is [ 1/2 m V2 .Initial KE of the kart = (1/2) (24) (1)2 = 12 joules.Final KE = (1/2) (24) (4)2 = 192 joules.Difference = amount of energy due to increased speed = (192 - 12) =180 joules.

Kinetic energy of a moving mass is [ 1/2 m V2 ].Initial KE of the kart = (1/2) (24) (1)2 = 12 joulesFinal KE = (1/2) (24) (4)2 = 192 joulesDifference = amount of energy due to increased speed = (192 - 12) = 180 joules.That additional energy had to come from somewhere ... most likely the shopper.A couple of things to notice from this discussion:1). The laws of nature, and Physics in particular, are remarkably constant. That's why the answerto this question, and the method of solution, are identical to the the answer given when the samequestion was submitted two days ago.2). The cart's final speed, 4 meters/sec, is about 8.9 mph, which is a shopping cart careeningdown the canned-vegetable aisle at 6min42sec per mile. I couldn't even do that in high-schoolcross-country. Look out shoppers !
How much work must be done on a 10kg bicycle to increase its speed from 2 M's to 3 M's?
Work done = increase in kinetic energy ie 1/2 * 10 * (3+2)(3-2) [recall a2 - b2 = (a+b)(a-b)] Hence work done = 25 joule.

When an average force F is exerted over a certain distance on a shopping cart of mass m its kinetic energy increases by 12mv2?
The work done on the shopping cart by the force is equal to the increase in its kinetic energy. Therefore, the work done is 12mv^2. If the force is exerted over a distance d, then the work done is also equal to Fd. Setting these two expressions equal gives you the relationship between the force, distance, and kinetic energy of the shopping cart.
Where do shopping carts go in a parking lot?
When you are done with your Shopping Cart, you can return it to the store, leave it in a Shopping Cart Corral, or a Shopping Cart Area, which usually says "Please return Shopping Carts Here!" Thank You or it may say " Please help keep costs low by returning your Shopping Cart Here! Thank You". If there are no cart corrals or such things like that in the parking lot, then leave it in the parking lot, just find a spot where a cart will fit, without damages any cars. Do Not Take Shopping Carts Off Store Premises!! It's the Law!!

How much work is done pushing a shopping cart 100 meters with a force of 88N?
The work done pushing the shopping cart would be 8800 Joules, calculated as force (88N) times distance (100m). Work is the product of force applied in the direction of motion and the distance over which it is applied.
What is the supermarket liability if a shopping cart strikes your vehicle?
answer: probably not as most supermarkets have signs saying they are not responsible for damage done to cars. You park at your risk. Besides, the fault is not that of the supermarket but of the person who didn't replace the cart.
You push a loaded shopping cart 5 meters along the ground with a force of 200 N What work have you done on it?
The work done on the shopping cart is 1000 joules (200 N * 5 m). Work is calculated by multiplying the force applied with the distance the force is applied over.
What does Item accepted mean while ordering online?
it means either you bought it or its "added to your shopping cart" as they say. No!! it means it is ready to ship but they havent done it yet
