You dive straight down into a pool of water. you hit the water with a speed of 6.5 m/s , and your mass is 70 kg . part a assuming a drag force of the form fd = (−1.10×104 kg/s ) v, how long does it take you to reach 2% of your original speed? (ignore any effects of buoyancy.)

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
