For a short time, a motor of the random-orbit sander drives the gear \( A \) with an angular velocity of \( \omega_A = 40(t^3 + 6t) \, \text{rad/s} \), where \( t \) is in seconds. This gear is connected to gear \( B \), which is fixedly connected to the shaft \( CD \). The end of this shaft is connected to the eccentric spindle \( EF \) and pad \( P \), which causes the pad to orbit around shaft \( CD \) at a radius of 15 mm. (Figure 1)**Part A**Determine the magnitude of the velocity of the spindle \( EF \) when \( t = 2.3 \, \text{s} \) after starting from rest.

The gear \( A \) drives the mechanism, connected to a gear system leading to a spindle \( EF \). Various distances and dimensions, such as the radius of the orbit (15 mm) and gear sizes (e.g., 60 mm, 40 mm, 10 mm), are shown to illustrate the gear connections and mechanical layout. The pad \( P \) orbits at the specified radius and is part of the eccentric spindle's motion.

For a short time a motor of the random-orbit sander drives the gear A with an angular velocity of WA-40(+³+6t) rad/s, where t is in seconds. This gear is connected to gear B, which is fixed connected to the shaft CD. The end of this shaft is connected to the eccentric spindle EF and pad P, which causes the pad to orbit around shaft CD at a radius of 15 mm. (Figure 1)
