A field has the following dimensions 52 m x 44 m. A person jogs along the edge of the field and runs 4.5 laps every day, starting from a vertex of the rectangle. If the entire distance is made in 1.23 minutes, what is the magnitude of the velocity (m/s)?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
