The velocity 2 s after throwing the object
WebAfter 1 second we know that the velocity changed by - 9.8 m/s so at this point in time the object is traveling at a velocity of (+ 29.4 m/s) + (- 9.8 m/s) = + 19.6 m/s. After another second, a total of 2 seconds, the velocity will have changed by another - 9.8 m/s so that … The ball's initial velocity is the one measured at its highest point and its final … That's not always the case, but it happens that in these two examples it was. So … Hence the 'V' in the first equation can be rewritten as "(Vf + Vi)/2", the AVERAGE … WebMar 26, 2016 · Here’s a simple example that shows how a simple constant acceleration can cause the speed to increase and decrease in the course of an object’s motion. Say you take a ball, throw it straight up in the air, and then catch it again. If you throw the ball upward with a speed of 9.8 m/s, the velocity has a magnitude of 9.8 m/s in the upward ...
