Question

1.If the object’s force is (4i-9j)N and it’s displacement is (8i+2j)m, what is the work done for object? 2]A 4kg block initially at rest is pulled to the right along a horizontal, frictionless surface by a constant horizontal force of 25N. Find the speed of the block after it has moved 4m. 3]A cart is loaded with a brick and pulled at constant speed along an inclined plane to the height of a seat-top. If the mass of the loaded cart is 4.210 kg and the height of the seat top is 0.195 meters, then what is the potential energy of the loaded cart at the height of the seat-top? (g=9.8m/ss 4]4.A vector’s point is (3,-2) , B vector’s point is (2,-5) and C vector’s point is (-3,-4). Find 2A+3C-B vector] 5.If the object’s kinetic energy is 240 J and its speed is 8 m/s. what is the acceleration of an object? ( The applied force of an object is 40 N)Immersive Reader
