Prove by solution that at the height of 55.86 meters of the Learning Tower of Pisa, Galileo's experiment is true for a 42g baseball and a 46g golf ball to hit the ground at the same time ; thus proving that acceleration due to gravity is constant.

A stone was release from a flying hot air balloon and hit the ground after 1.5 minutes. What was the height of the hot air balloon?( Neglect air resistance). What was the final velocity of the stone upon hitting the ground? ( Neglect air resistance). What is the stone's velocity after the 1 minute- fall? In another case, where air is blowing at a constant speed to the East of 100 m/s, what will the final velocity be, upon hitting the ground?

can a floating log of wood on the on a still water be considered in the state of equilibrium. Explain the answer

A total distance of travel of 1000 km breaks every 100 km of a pattern of East- South- East- South- continuously up to the end. The time of travel was recorded 5 hours. (a) Find the average velocity of the travel. (b) if the helicopter flies from the same origin, what will be it's average velocity in an hour travel?

When do you get a zero torque with respect to an acting force and the point of reference

The cause of acceleration in the freefall

A total distance of travel of 1000 km breaks every 100 km of a pattern of East- South- East- South- continuously up to the end. The time of travel was recorded 5 hours. (a) Find the average velocity of the travel. (b) if the helicopter flies from the same origin, what will be it's average velocity in an hour travel?
