# A bowling ball and a tennis ball are dropped at the same time. Ignoring wind resistance, which one will hit the ground first? Which will hit at a higher speed? What will be their accelerations?

You MUST watch the video of the bowling ball and FEATHER!! in a vacuum!!! Look for it on YouTube:

Watching the theory come to pass in a real experiment carried out in a massive vacuum chamber is incredible!

Both the bowling ball and the tennis ball will hit the ground at the same time. The bowling ball will hit the ground with a higher speed due to its larger mass. Their accelerations towards the ground will be equal, which is the acceleration due to gravity, approximately 9.8 meters per second squared downward.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- An object travels North at #3 m/s# for #8 s# and then travels South at #4 m/s# for # 6 s#. What are the object's average speed and velocity?
- If a car goes 0 to 60 mph in 7.5 seconds, and its initial velocity is 15 mph, what is its rate of acceleration, and how fast would it be going after 500 feet?
- An object has a mass of #2 kg#. The object's kinetic energy uniformly changes from #64 KJ# to #38 KJ# over #t in [0, 15 s]#. What is the average speed of the object?
- What is the speed of an object that travels from #( 8 , 4, 1 ) # to #( 6 , -1, 6 ) # over #4 s#?
- An object falls a distance h from rest. If it travels .50h in the last 1.00s, find (a) the time and (b) the height of its fall?
