a boy drops a rock off a cliff. how fast will it be traveling 2 seconds after he drops it?
v= gt= 2g
24
To determine the speed of the rock 2 seconds after it is dropped, we need to consider the force acting on it and the effect of gravity.
When an object is dropped, it will experience an acceleration due to gravity, which is approximately 9.8 m/s² on Earth. This means that every second, the velocity of the object will increase by 9.8 m/s.
To calculate the speed of the rock after 2 seconds, we can multiply the acceleration due to gravity by the time it has been falling.
Speed = Acceleration × Time
Speed = 9.8 m/s² × 2 seconds
Speed = 19.6 m/s
Therefore, the rock will be traveling at a speed of 19.6 m/s after 2 seconds of being dropped.
