Question

A coin released at rest from the top of a tower hits the ground after falling 2.7 s. What is the velocity of the coin as it hits the ground?

a) 26.46 m/s

b) 13.23 m/s

c) 9.8 m/s

d) 19.6 m/s

Answer 1

The velocity of the coin as it hits the ground is 26.46 m/s.

Step-by-step explanation:

The velocity of the coin as it hits the ground can be calculated using the equation:

V = gt

Where V is the velocity, g is the acceleration due to gravity, and t is the time it takes for the coin to hit the ground.

In this case, the time is given as 2.7 seconds and the acceleration due to gravity is approximately 9.8 m/s^2.

Substituting these values into the equation, we have:

V = 9.8 * 2.7 = 26.46 m/s

Therefore, the velocity of the coin as it hits the ground is 26.46 m/s.
