If an object is dropped from a height of 45 meters, what is its speed just before it hits the ground? (Take g=10m/s2)
To find the speed of an object just before it hits the ground when dropped from a height, we can use the kinematic equation:
Where:
v is the final velocity just before hitting the ground
v0 = 0m/s (initial velocity)
g = 10 m/s2
h = 45m (height).
Substituting the known values into the equation gives:
