A ball is dropped from the top of a building of height 100m

Assuming the balls were dropped from a great enough height to attain their respective terminal velocities the golf ball would hit the ground first. This is because the tennis ball has a larger surface area (and is usually rougher) which means it will create more drag which will cause more air resistance which will result in a lower terminal ...
