A block of mass m = 7.19kg is free to move along the x-axis of a rough horizontal surface. The mass is subject to the force of gravity, a normal force, a force of kinetic friction, and a position-dependent force. The coefficient of kinetic friction is μ = 0.363. The position-dependent force is given by F(x) = (22.05x – 9.34x²)î. When the block is at ri 1.02mi it moves with velocity v₁ = 8.17. (The input below will accept answers with no more than 1% variation from the correct value.) What is the kinetic energy of the block when it is at 7₂ J = = 1.02mi?
