If you throw a 36 kilogram rock off a cliff , how fast does it accelerate to the ground? The earth excerts a force of 200 Newtons on the rock.
To determine the acceleration of the rock, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula is:
a = F/m
where:
a = acceleration
F = force acting on the object
m = mass of the object
In this case, the force acting on the rock is 200 Newtons and the mass of the rock is 36 kilograms. Plugging these values into the equation, we can calculate the acceleration:
a = 200 N / 36 kg = 5.56 m/s²
Therefore, the rock will accelerate towards the ground at a rate of 5.56 meters per second squared.
