Which object would have the slowest speed at terminal velocity?

a 50-kilogram block with no parachute

a 50-kilogram block with a large parachute

a 10-kilogram block with a small parachute

a 10-kilogram block with no parachute

The 50-kilogram block with a large parachute would have the slowest speed at terminal velocity, as the parachute would create more air resistance and slow down the fall of the block.
