janaki Posted November 13, 2013 Posted November 13, 2013 a stone is thrown upward an initial speed of 20m/s. it goes up to a certain height, then comes down to the same level from where it was thrown. assume ag= -9.8m/s^sa. how high does the stone go before it starts to come down? how long does it take the stone to reach this point?b. what is the acceleration of the stone at the highest point it reached? what is its speed at the highest point?c. how long does it take the stone to reach the same level from where it was thrown??
swansont Posted November 13, 2013 Posted November 13, 2013 What have you done on the problem so far? Do you know of a relationship that tells you the height in terms of other things you know?
