A kangaroo is hopping about downtown sydney, looking for some grub. If \(∆k\) represents the change in kinetic energy of the body and \(w\) represents the work done on it. We know that all the car’s kinetic energy is lost to friction.
W = F X Cos (Θ).
If a child applies a 3 n force for 2 m in the same direction the car is already moving, how much work is done on the car? W = f x cos (θ). The mass of the sled plus gifts is 60 kg and he drags the sled at an angle of 20° for 12 meters.
The Amount Of Work Done By A Steady Force Is The Amount Of Force Multiplied By The Distance An Object Moves Parallel To That Force:

Add Up The Total Amount Of Work Done By Each Force.
Potential energy stored in a spring. The object is pulled 12\text { m} 12 m at an angle of 15^\circ 15∘ with the horizontal. By using work and energy theorem we say that;
What Is The Kinetic Energy Of The Car?
In the diagram below, the spring has a force constant of 5000 n/m, the block has a mass of 6.20 kg, and the height h of the hill is 5.25 m. W = work, ke = kinetic energy. We know that all the car’s kinetic energy is lost to friction.
The Units Are N · M, Which Equal A Joule (J).
W net = 1200 joule. Use this version, or check out other variations created by teachers from the wizer community: When work done on an object increases only its kinetic energy, then the net work equals the change in the value of the quantity 1 2 m v 2 1 2 m v 2.
