x = (1/2)gt2
x = (1/2)(9.8)(2.5)2
x = 30.625m
the earth doesnt fall.
186.2824 miles.
880 feet.
Yes the seeds fall away in balsam plant due to explosive opening of its fruits.
First, watch for lightning. The second it hits the ground, starts counting in seconds. Stop when you hear thunder. divide the seconds by 5 to get how many miles away the lightning is. For kilometers, divide the seconds by 3.
490 meters
78.46 meters (257.4 feet)
1,100 to 1,300 feet.
576 feet
It has been known since the 16th century that the mass of an object is irrelevant to how far it will fall. The main factor influencing the rate of fall is the shape of the object and, therefore, the air resistance (or buoyancy).
122.5 meters (402.5 feet)
160 m
depends on the mass of the stone, the shape of the stone, and the height dropped from. sorry dude.
The answer depends on:where it is falling (if on a space ship, the answer may be 0)the extent to which air resistance affects the fall.
Because this is a free fall questions, the equation d=1/2gt² can be used. Gravity is a given, 9.8 m/s² and the time is your 15 seconds of free fall. d=1/2(9.8m/s²)(15s)²= 1,102.5m. To find feet multiply 3.28084 to answer because that is how many feet are in a meter.
IF the object begins from rest, then it travels 1.5 x 10^8 meters. (rounded)
a few things missing: - How fast is the acceleration? - How long does it take to go from 4ms to 20ms?
