### Question

An object is released from rest at a height of 25m. Calculate the time it takes to fall to the ground. [g = 10ms-2]

### Options

A) 25.00s

B) 10.00s

C) 2.50s

D) 2.24s

t = $$\sqrt{\frac{2s}{g}} = \sqrt{\frac{2 \times 25}{10}} = 2.24$$
• t = $$\sqrt{\frac{2s}{g}} = \sqrt{\frac{2 \times 25}{10}} = 2.24$$
