Astudent throws a coin vertically downward from the top of a building. the coin leaves the throwers hand with a speed of 15.0 m/s. what is the magnitude of its velocity after falling 10.0 m? a.) 18.0 m/s b.) 14.5 m/s c.) 20.5 m/s d.) 19.8 m/s

The correct answer is option C

Explanation:

We have the equation of motion, , where v is the final velocity, u is the initial velocity, a is the acceleration and s is the displacement.

Here initial velocity = 15 m/s

  Displacement = 10 m

  Acceleration = acceleration due to gravity = 9.8 m/s²

Substituting to get final velocity,

So the correct answer is option C
