1. The following four forces pull on a point. 15 N due

1. The following four forces pull on a point. 15 N due East, 20 N 55 North of East, 10 N 75 North of West, and 20 N 65 South of West. Calculate the resultant force and the direction. 2. A motorcycle uniformly accelerates from 0 to 71.5 m/s at 5.1 seconds. What is the acceler- ation and the distance travelled? 3. A 26 kg splined shaft, rotating freely at 400 rpm, and having a radius of gyration of 42.4 mm, engages a 14.6 kg stationary gear. When engaged, the combined radius of gyration of shaft and gear is 47.6 mm. Find the final rotational speed of the combined shaft and gear. + + Towe
