KOP: Force and Acceleration - General Questions

16.

A particle having a mass of 1.5 kg, moves along a three-dimensional path defined by the equations r = 94 + 3t) m, = (t² + 2) rad, and z = (6 - t³) m, where t is in seconds, and the z-axis is vertical. Determine the r, , and z components of force which the path exerts on the particle when t = 2 s.

F_r = 0, F₂ = 30 N, F_z = -18.00 N

F_r = -240 N, F₂ = 66.0 N, F_z = -3.29 N

F_r = 0, F₂ = 3 N, F_z = -18.00 N

F_r = -160.0 N, F₂ = 44.0 N, F_z = -12.00 N
