The motor, M. pulls on the cable with a force = F (10t2 +300) N, where t is in seconds. Neglect the mass of the cable and pulleys. (Figure 1) Figure 1 of 1 Part A If the 100 kg crate is originally at rest at t=0, determine its speed when t = 4.5 s. Hint First find the time needed to begin lifting the crate.
