Question

A coin is dropped off a 350m skyscraper how long does it take the coin to hut the ground?

A) 5 seconds
B) 10 seconds
C) 15 seconds
D) 20 seconds

Answer 1

The coin takes approximately 8.86 seconds to hit the ground

Step-by-step explanation:

To determine how long it takes for the coin to hit the ground, we can use the equation of motion for an object in free fall: d = (1/2)gt^2, where d is the vertical distance fallen, g is the acceleration due to gravity, and t is the time taken. In this case, the height fallen is 350 m, so we can rearrange the equation to solve for t:

t = sqrt((2d)/g)

Substituting the given values, t = sqrt((2 x 350)/9.8) = 8.86 seconds. Therefore, the answer is not listed among the options provided.
