Question

If a crate with a mass of 100 kg, moving at 28 m/s, falls to the ground, what is the distance it falls?

a) 280 m
b) 560 m
c) 1120 m
d) 1960 m

Answer 1

The distance the crate falls is 41.70 meters.

Step-by-step explanation:

To find the distance the crate falls, we can use the kinematic equation for free-falling objects:

d = (1/2) * g * t^2

In this equation, d is the distance, g is the acceleration due to gravity (9.8 m/s^2), and t is the time. To find the time, we can use the equation:

t = v / g

where v is the initial velocity of the crate. Plugging in the values: t = 28 / 9.8 = 2.86 seconds. Now we can calculate the distance:

d = (1/2) * 9.8 * (2.86^2) = 41.70 meters.
