You apply a constant force of F = (1.9 N) i - (4.9 N) j– (8.6 N) k to an object as it undergoes a displacement s = -(6.6 m) i + (8.1m) j– (3.6 m) k. Calculate the work done by the force you apply. Ž: A block of ice with mass 2.1 kg is initially at rest on a frictionless, horizontal surface. A worker then applies a horizontal force F to it. A a result, the block moves along the x-axis such that its position as a function of time is given by x(t) = 0.21 (m/s²) t² + 0.012 (m/s³) t³. Calculate the work done by the force during the first 1.1 s of the motion. Ž:
