Ex.3An object of mass 2 kg. vertical, straight from the stop with the constant acceleration 3 m/s2.Once past the point of observation, with the speed of 12 m/s.While the subject has 24 m/s velocity, the object a few meters away from the observation point. How to make a.The proposition asked for long distance observation, to the final point.= The start to the last one-the start to the point of observation. 1. find the distance from the start point to end point.S = ? A = 3U = 0 T = --V = 24 v2 = u2 + 2as 242 = 02 + 2(3)(s)576 = 0 + 6ss = 96 m 2. find the distance from the start point to the point of observation.S = ? A = 3U = 0 T = --V = 12 v2 = u2 + 2as 122 = 02 + 2(3)(s)144 = 0 + 6ss = 24 m Therefore, stay away from the point of observation = 96-24 = 72 m.
