Answer:
Explanation:
The equation of equlibrium for the box is:
The formula for the acceleration, given in , is:
Velocity can be derived from the following definition of acceleration:
The speed after the box has travelled 17 meters is:
Rocks,Fossils,Carbon dating
I belive it could be 6.5 but I could be wrong
Answer:
It took the rock 2 seconds to get to the water from the bridge.
Explanation:
Since Forrest drops the rock, it means its initial velocity is zero, and because it is freely falling under the influence of gravity, after time it will gain a velocity of
,
solving for we get:
Since in our case the velocity the rock gained was and the acceleration due to gravity is , we have
Thus, the time took the rock to reach the water from the bridge was 2 seconds.
