Astone is thrown with an initial speed of 15 m/s at an angle of 53° above the horizontal from the top of a 35 m building. if g = 9.8 m/s2 and air resistance is negligible, then what is the magnitude of the vertical velocity component of the rock as it hits the ground?

The magnitude of the vertical velocity component of the rock as it hits the ground is 28.93 m/s.

The given parameters;

The time of motion of the stone is calculated as follows;

The magnitude of the vertical velocity component of the rock as it hits the ground is calculated as;

Thus, the magnitude of the vertical velocity component of the rock as it hits the ground is 28.93 m/s.

answer: electrons

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
