Forces problem: a donkey pulling a cart - Physics Forums
2006年2月23日 · A 255 kg donkey is pulling on a cart with a horizontal force of 1940 N. The mass of the cart is 520 kg and the cart is rolling at a constant velocity of 0.72 meters / second to the left. Find:
How Do We Calculate Kinetic Friction and Net Force in a Donkey …
2008年10月23日 · A 255[kg] donkey is pulling on a cart with a horizontal force of 1940[N]. The mass of the cart is 520[kg] and the cart is rolling at a constant velocity of 0.72[m/s] to the left. Find: a) The coefficient of kinetic friction for the wheel’s bearings of the cart. b) The NET force (magnitude and direction) exerted by the surface on the donkey
Another Action/Reaction question Donkey and a cart - Physics …
2006年10月2日 · How does Newton's Third Law apply to the scenario of a donkey pulling a cart? Newton's Third Law states that for every action, there is an equal and opposite reaction. In this scenario, the action is the force exerted by the donkey on the cart, and the reaction is the force exerted by the cart on the donkey.
Is this scientific idea really feasible? - Physics Forums
2010年8月22日 · In the magnet situation, the magnet is pulling the truck, but also the truck is pulling the magnet back equally, and as a result their center of masses stays immobile. In the donkey situation, the carrot is pulling the donkey but the donkey is not pulling the carrot back, so you end up with a net impulse gain ;)
Newton's third law in ropes and tension - Physics Forums
2014年8月6日 · b) If two people pull on a rope with equal force (say, 100 N), each person pulling feels their own force (Newton's 3rd law) plus the force the other guy exerts. Why is the tension not 200 N then? c) If you could also explain what really happens in (b) with another combination of forces (non-equal), addressing how Newton's third law works in ...

Physical Explanation of a Pull-Back Car - Physics Forums
2005年1月9日 · FAQ: Physical Explanation of a Pull-Back Car What is a pull-back car? A pull-back car is a toy car that is powered by a mechanism that involves pulling the car back and then releasing it to propel it forward. The energy created by pulling the car back is stored in a spring or rubber band, which is then released to move the car forward.
How Does Trailer Weight Impact the Work Done by a Car?
2012年5月4日 · In summary, the conversation discusses the calculation of work done by a car in pulling a trailer of weight 2500 N for a distance of 8 km. The answer is determined to be 160,000 J. The concept of change in energy and its relation …
How Should Forces Be Calculated in a Truck-Trailer System?
2015年1月16日 · What safety precautions should be taken when truck pulling trailer? When truck pulling trailer, it is important to ensure that the trailer is properly attached to the truck, the cargo is loaded and secured correctly, and the truck is in good working condition. It is also important to follow traffic laws and maintain a safe speed while driving.
