You drop a coin from the CN tower. Air resistance is not negligible. Describe the motion of the coin. It accelerates at -g until the coin reaches terminal speed, and then has constant speed. It accelerates at -g until it hits the ground. It falls at constant speed until it hits the ground. Its acceleration is initially -g, but its magnitude gradually decreases to zero as the coin falls.

A physics book of unknown mass is dropped 5.00 m. What speed does the book have just before it hits the ground? Assume that air resistance is negligible.

A body is dropped from a tower with zero velocity reaches the ground in 10s.  The height of the tower is about :(given : g = 10 m/s2)            A 150 m B 200 m C 50 m D 500 m

True or False: All objects fall at different speeds because of air resistance

A paper ball is released from rest, and goes on to fall through a large vertical distance. As it falls through the air, it is acted upon by two forces – air resistance and its weight. Which of the following correctly describes its motion after it is dropped?It will accelerate at an increasing rate and then reach its terminal velocityIt will accelerate uniformly before reaching its terminal velocityIt will accelerate uniformlyIt will accelerate at a decreasing rate and then reach its terminal velocity

When an object falls faster, its air resistance ______.Multiple choice question.increasesdecreasesremains constant
