Answer to Question #150729 in Physics for ara

Question

Gabi threw a 145 g baseball upwards with an initial speed of 25 m/s. How fast is the ball moving after 1 second?

Answer 1

We can find the velocity of the ball after 1 second from the kinamatic equation:

$$v=v_0-gt=25\ \dfrac{m}{s}-9.8\ \dfrac{m}{s^2}\cdot 1\ s=15.2\ \dfrac{m}{s}.$$

Answer:

$v=15.2\ \dfrac{m}{s}.$
